Sidebar refresh:
- addFile/addFolder now use currentFolderId || selectedNode.id as parent
- startImport stores pendingImportParent; confirmImport uses it
- setNodeChildren also updates node.has_children for toggle arrow reactivity
- navigateToFolder expands the folder node in sidebar tree
Context menu position:
- FileTreeRow stores menuX/menuY from contextmenu event coords
- Menu uses position:fixed with cursor-relative left/top and window clamp
Show in explorer:
- Sidebar context menu uses file.showInExplorer label
- en.js: add file.showInExplorer key
