refactor(frontend): extract FilesTab from App.svelte

• Create lib/components/files/FilesTab.svelte (616 lines)
  - Self-contained file browser with internal state
  - Folder navigation, breadcrumbs, file list
  - File preview with CheckFileAction for .md → note editor flow
  - Import dialog (copy/link)
  - Drag-and-drop, selection, keyboard shortcuts
  - Cut/copy/paste, rename, delete, duplicate
  - Public API: resetToNode(), filesHandleKeydown()
• Remove ~594 lines from App.svelte (4794 → 4200)
  - Removed: loadingFiles, currentFolderId, folderStack, fileItems,
    previewItem/Content/Loading/Error, clipboard, selectedIds, dragIds,
    importing, importSummary, showImportDialog, pendingImportPath/Parent,
    treeItems, expanded, childrenMap, dropRootValid, inboxDropValid,
    captureDropActive/Label/DragDepth/lastCaptureDragOverAt/captureDragResetTimer
  - Removed: loadTree, loadFolder, navigateToFolder, navigateBack,
    navigateToBreadcrumb, openPreview, closePreview, createFile,
    duplicateItem, renameItem, cutItem, copyItem, pasteItem,
    toggleSelection, selectOne, selectAll, rangeSelect, clearSelection,
    getTargetIds, deleteSelected, cutSelected, copySelected,
    onDragStart, onDragOver, onDrop, openSelected, openSelectedExternal,
    addFile, addFolder, startImport, confirmImport, cancelImport, deleteFile
  - Keyboard handler delegates to filesTabRef.filesHandleKeydown()
  - selectNode() calls filesTabRef.resetToNode()
• Update docs/frontend-architecture.md — Files Flow section
• Update docs/frontend-change-map.md — Phase 2 & 5 marked complete
• Build passes: npm run build ✓, go test ✓, build.sh gui ✓

+# Verstak project rules
+
+## Project quality rule: no MVP shortcuts
+
+This project is not an investor demo, not a throwaway prototype, and not a “good enough for MVP” product.
+
+Do not justify known inconsistencies, broken invariants, unsafe behavior, architectural shortcuts, or incomplete data-model operations by calling them “MVP acceptable”.
+
+If you find a mismatch between logical state and physical state, treat it as a bug unless the project owner explicitly says otherwise.
+
+For Verstak specifically:
+
+* Rename must keep logical metadata and filesystem representation consistent, or the design must explicitly document why filenames are stable IDs and not display names.
+* Delete must remove or tombstone all related state consistently.
+* File paths must never depend on unsafe user input.
+* Database state and filesystem state must not silently diverge.
+* “Works because the file is not lost” is not enough.
+* “Can be fixed later” is not an acceptable reason to leave architectural debt.
+* If a feature cannot be completed properly in the current step, stop and report it as incomplete, with a concrete fix plan.
+
+Use these categories in reports:
+
+1. Done — implemented and tested.
+2. Incomplete — implemented partially, must not be treated as finished.
+3. Blocked — cannot continue without a decision.
+4. Design decision required — multiple valid approaches exist.
+5. Known bug — must be fixed before moving on.
+
+Forbidden report pattern:
+
+> This is acceptable for MVP.
+
+Required replacement:
+
+> This violates the current project invariants. I either fixed it, or I am reporting it as incomplete and proposing the smallest correct fix.
+
+
+
+## Project identity
+
+Verstak is a local-first workbench for clients, projects, notes, files, tasks, activity and sync.
+It must remain practical, simple, and filesystem-aware.
+
+## Stack
+
+- Backend: Go
+- Storage: SQLite
+- GUI: Wails v2
+- Frontend: Svelte 4
+- Build tooling: Vite 5
+- Do not migrate to Wails v3, Svelte 5, or Vite 8 unless explicitly asked.
+
+## Architecture rules
+
+- Keep local-first behavior.
+- Do not turn the project into SaaS.
+- Do not replace SQLite with another database.
+- Do not introduce cloud storage assumptions.
+- Preserve recursive folder import semantics.
+- Preserve stable node IDs.
+- Do not duplicate nodes when moving items.
+- Do not create parallel state systems for the same entity.
+
+## UI rules
+
+- Fix GUI behavior at root cause.
+- Do not redesign the whole interface unless explicitly asked.
+- Preserve active tab state correctly.
+- Context menus must open near the cursor.
+- Drag-and-drop must show clear visual target feedback.
+- Moving nodes must never duplicate the same ID in two places.
+- Nested selection must not collapse the parent unexpectedly.
+
+## Files
+
+- File view is not a tree.
+- Sidebar shows logical hierarchy.
+- Vault filesystem layout must remain human-readable without the app.
+- Drag-and-drop folders must perform real recursive copy/move into the vault.
+- Do not fake folder support with external links.
+
+## Sync
+
+- Sync settings belong in Settings.
+- Main UI may keep only manual sync/status controls.
+- Existing URL + login/password device registration flow should be preserved unless explicitly changed.
+- Secrets must not be logged.
+
+## Verification
+
+For backend changes:
+- Run `go test ./...` if possible.
+
+For frontend changes:
+- Run the relevant frontend build/check command if available.
+- If unsure, inspect package scripts first.
+
+For GUI bugs:
+- Add targeted tests only where practical.
+- If manual GUI clicking is required and unavailable, state exact manual verification steps for the user.
+
+
+# Session summary
+
+## Bugs fixed (this session)
+1. **webkit2_41 build tag** — binary wouldn't start without it. Added to build instructions.
+2. **Sidebar refresh** — `reloadTreePreservingExpanded` patches children in-place so expand/collapse state stays intact.
+3. **Context menu off-screen** — changed to `position: fixed` with cursor coordinates.
+4. **"Show in explorer" only for folder types** — `OpenFolder` in backend falls back to file record path for `TypeFile` nodes.
+5. **Context menu not closing on action** — `handleShowInFolder` calls `closeMenu()`.
+6. **Wrong folder when opening file's parent folder** — `OpenFolder` checks `n.FsPath == ""` for TypeFile and uses first file record path.
+7. **Tab highlight not updating visually** — was using `class={tabClass(tab.id)}` which didn't trigger reactive class updates in Svelte. Switched to `class="tab" class:active={activeTab === tab.id}`.
+8. **Journal table expand/collapse** — added explicit ▸/▾ toggle column so it's clear rows are expandable.
+9. **Per-node worklog entries** — made entries expandable with ▸/▾, showing details + billable/approximate tags.
+10. **Manual worklog entry form** — converted inline form to modal dialog ("+ Добавить запись") with all fields: date, summary, minutes, details, billable, approximate.
+11. **"С подзадачами" → "Учитывать вложенные дела"** — renamed, now hidden when no node selected.
+12. **Filter/export layout** — split into separate "Фильтры" and "Экспорт отчёта" sections with headings.
+13. **Suggestion events** — added "Показать в проводнике" button for file-type events in suggestion detail.
+14. **Removed duplicate i18n keys** in `ru.js` (worklog.suggestions, worklog.apply).
+15. **Removed unused CSS** (`.journal-filters`, `.wl-meta`, `.worklog-form`).
+16. **Added `openNodeFolder(nodeOrId)`** — accepts both string ID and node object.
+17. **Added `resetJournalFilters()`** — resets all filters and reloads.
+18. **Source field** — added `worklog_entries.source` column (migration 014). Values: manual, suggestion. Old entries default to 'unknown'.
+19. **Suggestions now use worklog_entry_events** instead of `HasTodayEntries` — only events already linked to worklog entries are excluded. Repeated activity on the same node today now produces new suggestions.
+20. **Activity target navigation** — clicking activity events for notes opens the note tab and loads the specific note. File events open the files tab.
+21. **Source display** — detail sections now show accurate source: "Ручная запись", "Из предложения", "Из предложения, но связанные события отсутствуют", or "Источник неизвестен".
+22. **Wails `[]string` marshalling bug** — Wails v2.12.0 silently drops `[]string` positional args from JS→Go. **Fix**: pass all string arrays as `JSON.stringify()` → `string` → `json.Unmarshal` on Go side.
+23. **Event link validation** — `AcceptSuggestionWith` pre-checks each eventID against `activity_events`, uses plain `INSERT` (not `INSERT OR IGNORE`), and verifies with JOIN `COUNT(*)` after commit.
+24. **GetWorklogEntryEvents column fix** — query used `e.details_json` but the column is `e.metadata`. Fixed to `COALESCE(e.metadata,'')`.
+25. **"Посмотреть" button** — `openActivityTarget(ev)` navigates to the specific target: note tab + open note for `targetType=note`, files tab + `OpenFolder(targetPath)` for `file/folder`.
+26. **End-to-end test** — `TestAcceptSuggestionWithEndToEnd` creates node, 3 activity events, accepts suggestion, verifies all 3 linked via `worklog_entry_events` + JOIN.
+27. **WriteDebugLog binding** — `bindings_debug.go` writes frontend logs to `<vault>/.verstak/debug.log` for production GUI debugging.
+28. **Journal regression tests** — `TestJournalFullRegression`, `TestSuggestionOnRepeatedActivity`, `TestManualWorklogEntry`.
+29. **resolveActivityTarget helper** — pure function returning `{ nodeId, tab, noteId/fileId/targetPath }`, used by `openActivityTarget`.
+30. **First-run flow** — no auto-vault creation. New `GetStartupStatus` binding returns `first_run`/`recovery`/`ready`. Frontend shows FirstRun.svelte or VaultRecovery.svelte accordingly.
+31. **Global config.json** — moved vault path, sync settings, templates, theme, language from implicit CLI args to `~/.config/verstak/config.json` (`AppConfig` struct).
+32. **Sync settings in Settings** — extracted sync modal into Settings → Sync section. Removed all inline sync form fields from `App.svelte`. Added `SyncStatus.svelte` widget replacing navbar sync button.
+33. **Settings window** — modal with sidebar (8 sections: General, Workspace, Templates, Plugins, Files, Activity, Sync, Backup). ESC to close. Lazy-loaded content panels.
+34. **Template enable/disable** — `AllTemplates` + `SetTemplateEnabled` bindings propagate to `appCfg.EnabledTemplates`. `initVault` applies filter to registry.
+35. **Vault recovery screen** — when vault path exists but vault is missing, shows VaultRecovery.svelte with choose/create/quit options.
+
+## Bugs fixed (this session)
+
+1. **Trash preview "trash file not found" for TypeFile nodes** — `resolveTrashPath` only searched `<nodeID>_*` in trash dir, but TypeFile node files are moved by file record ID (`<recordID>_<filename>`). Added file record fallback via `ListTrashedByNode` + `ReadTrashFile(trashFsPath)` binding.
+2. **Trash restore creates empty files** — `DeleteToTrash` permanently `DELETE`'d file records from DB and `restoreTrashPath` silently `return nil` for `FsPath=""` nodes. Changed `deleteFileRecords` to `trashRecord` (sets `missing=1`, keeps record). `restoreTrashPath` now restores file records: moves file back from trash, sets `missing=0`.
+3. **`resolveTrashPath` inner loop corrupts `anc` variable** — `anc = child` inside the inner loop caused wrong path computation for nesting depth > 2. Replaced with direct `chain[0].FsPath` prefix computation.
+4. **`ListTrash` missing `TrashFsPath` for TypeFile nodes** — Phase 1 only checked `<nodeID>_*` entries. Added `ListTrashedByNode` fallback to set `TrashFsPath` for TypeFile nodes.
+5. **`ListByNode` returning trashed records** — Added `AND missing != 1` filter to exclude trashed file records from active node file listings.
+
+## Key patterns (this session)
+
+- **TypeFile node trash**: files are moved by file record ID (`<recordID>_<filename>`), NOT by node ID. Never search by `<nodeID>_*` alone — always fall back to file records via `ListTrashedByNode`.
+- **File record soft-trash**: use `UPDATE files SET missing=1` instead of `DELETE` to keep records restorable. Restore via `UPDATE ... SET missing=0` + `os.Rename` from trash.
+- `ReadTrashFile(trashFsPath)` is preferred over `ReadTrashFileContent(nodeID)` — frontend has `trashFsPath` precomputed by `ListTrash`.
+- **`restoreTrashPath` for TypeFile nodes**: when `fsPath == ""`, find file records with `missing=1` and restore each one.
+- **Full test coverage**: `TestTrashTypeFilePreviewAndRestore`, `TestTrashTypeFileInsideFolderRestorePreservesContent`, `TestTrashTypeFileMultipleRecords`.
+
+## Key patterns
+- Always use explicit toggle icons (▸/▾) on expandable rows.
+- `CreateWorklogFull` supports all fields: nodeID, summary, details, date, minutes, approximate, billable.
+- `openNodeFolder(id)` accepts a string ID or a node object.
+- `GetSuggestions` filters out only events already in `worklog_entry_events`, not entire nodes.
+- New worklog entries get `source=manual` via `Add`/`AddWithDate`; suggestion entries get `source=suggestion` via `AcceptSuggestionWith`.
+- **NEVER pass `[]string` through Wails v2 bindings** — always JSON-serialize to `string` first. Wails v2.12.0 silently drops slice arguments.
+- **Always wrap create-entry + link-events in a transaction** with pre-validation and post-commit verification to prevent orphan entries.
+- Frontend debug logs in production: use `wailsCall('WriteDebugLog', msg)` → writes to `<vault>/.verstak/debug.log`.
+- `AppConfig` stores all global settings in `~/.config/verstak/config.json`. Vault-specific config stays in `.verstak/config.yml`.
+- Use `GetStartupStatus` to determine first-run vs recovery vs normal startup.
+- Settings window uses a sidebar with 8 sections; each section is a separate Svelte component imported lazily.
+- Template enable/disable state is stored in `appCfg.EnabledTemplates` and applied to the registry during `initVault`.

 # Верстак
 
-**Верстак** — локальная программа, где по каждому клиенту или проекту
+**Верстак** — local-first рабочий vault. Всё организовано вокруг **дел**, а не задач.
-лежат все его файлы, заметки, документы, ссылки, действия и история работ.
 
-Это не замечатель, не CRM, не таск-трекер. **Нишевая аудитория** — люди,
+Дело может быть: клиентом, проектом, набором документов, рецептом, архивом, разовой работой.
-у которых работа организована через дела, а не через задачи:
+Внутри дела: вложенные папки, Markdown-заметки, файлы, действия (URL/файл/папка/команда), журнал работ, история активности.
-
-```
-дело → файлы → заметки → документы → действия → история → вернуться через месяц
-```
-
-## Для кого
-
-Один продукт — разные входные двери:
-
-| Кто | Как видит Верстак |
-|-----|-------------------|
-| Фрилансер / дизайнер | клиентские проекты, файлы, правки, история работ |
-| Мастер по ПК | клиенты, устройства, серийники, фото, журнал |
-| Разработчик | локальный workspace: заметки, репы, команды, файлы |
-| Писатель / мейкер | мастерская проектов: материалы, заметки, версии, история |
-
-## Универсальные сущности
-
-Базовая модель предельно проста — плагины добавляют функционал:
-
-- **Дело** — контекст для всего остального
-- **Заметка** — Markdown внутри vault
-- **Файл / Документ** — любой файл, привязанный к делу
-- **Действие** — кнопка запуска: URL, файл, папка, команда
-- **Журнал** — записи о затраченном времени
-
-Плагины (шаблоны дел, календарь, канбан, импортёры) расширяют
-эти сущности без перекомпиляции программы.

+## Быстрый старт
+
+### Требования
+
+- Go 1.25+
+- Node.js 20+
+- libwebkit2gtk-4.1-dev, libgtk-3-dev и другие Wails-зависимости (см. [wails.io/docs/desktop/linux](https://wails.io/docs/desktop/linux))
+- npm
+
+### Сборка
+
+```bash
+# Всё сразу (GUI + сервер)
+./scripts/build.sh
+
+# Или по отдельности
+./scripts/build.sh gui      # только GUI
+./scripts/build.sh server   # только сервер
+```
+
+Проверка GUI перед коммитом:
+
+```bash
+./scripts/check-gui.sh
+```
+
+Она проверяет локали, production-сборку фронтенда, актуальность embedded Wails assets и компиляцию GUI-бинаря.
+Дополнительно запускается headless Chromium smoke через Wails-mock: проверяются first-run, recovery, основное окно, Settings, workspace, вкладки дела, файлы, журнал, активность и мобильный viewport. Smoke выполняет реальные UI-действия: создание заметки, запись worklog, создание узла, вход в папку и возврат назад, а также Sync Now с предупреждениями о conflicts/applyErrors. Скриншоты пишутся в `/tmp/verstak-gui-smoke`.
+
+Бинарники попадают в `build/`:
+- `verstak` — GUI-приложение
+- `verstak-server` — опциональный сервер синхронизации
+
+### Запуск
+
+```bash
+# GUI (после сборки)
+./build/verstak
+
+# Сервер (после сборки)
+./build/verstak-server --help
+
+# CLI
+go run ./cmd/verstak/ --help
+```
+
+## Firefox Extension
+
+Расширение для Firefox — `extension-firefox/`. Распространяется как signed XPI: **Mozilla только подписывает** XPI через AMO (unlisted channel), а мы самостоятельно хостим signed XPI и управляем обновлениями через `updates.json`.
+
+### Сборка (unsigned)
+
+```bash
+./scripts/build.sh firefox
+# → build/verstak-bridge-firefox-unsigned.zip
+```
+
+### Подпись (требуются AMO-токены)
+
+```bash
+# 1. Скопировать .env.example → .env и заполнить WEB_EXT_API_KEY / WEB_EXT_API_SECRET
+cp .env.example .env
+
+# 2. Установить зависимости
+cd extension-firefox && npm install && cd ..
+
+# 3. Подписать XPI
+./scripts/sign-firefox-xpi.sh
+# → web-ext-artifacts/*.xpi
+
+# 4. Полный релиз: подпись + release/firefox/ + updates.json
+./scripts/release-firefox-xpi.sh
+# → release/firefox/verstak-firefox-VERSION.xpi
+# → release/firefox/updates.json
+```
+
+### Firefox Release Artifacts
+
+```
+release/firefox/verstak-firefox-VERSION.xpi
+release/firefox/updates.json
+```
+
+Обновления: Firefox проверяет `update_url` из manifest.json, указывающий на наш `updates.json`. При выходе новой версии достаточно:
+1. Подписать новый XPI
+2. Заменить файл на сервере
+3. Обновить `updates.json`
+
+## Release
+
+```bash
+# Полная сборка с упаковкой в DEB/RPM
+./scripts/release.sh               # dry-run (без git tag); требует AMO токены
+./scripts/release.sh --publish     # с git tag + GitHub release
+
+# Без подписи Firefox
+./scripts/release.sh --skip-firefox-sign
+```
+
+Артефакты релиза (после `./scripts/release.sh`):
