fix: tree DnD — correct cycle detection, reactive indicators, canonical reload

Backend: - Fix MoveNode validation: wouldCreateCycle walks from newParentID up toward root, rejects if nodeID is encountered (parent into descendant) - Allow moving descendant to ancestor (C into A) and child to root - Add isContainerType validation for new parent - Add 8 tests covering all scenarios + duplicate ID invariant Frontend TreeNode.svelte: - Build parent map from full tree (not just loaded children) - canDrop uses parent map for cycle detection - Reactive drop-valid/drop-invalid CSS via pre-computed dropAllowed map - Keyed {#each nodes as node (node.id)} for correct identity tracking - Auto-expand container on 600ms drag-over hover - Proper dragleave detection (ignore transitions to child elements) - Clean up state on dragend Frontend App.svelte: - reloadTreePreservingExpanded: fresh roots + children (no patching) - Root area visual drop indicator (dashed outline) - dragleave handler for root area Clean up stale GUI dist assets
