Outerline 1.0-44

Summary

Sidebar folder drag-and-drop reparenting build. You can now nest folders by dropping them onto another folder, or move them back to the library root by dropping onto All Documents. Invalid nesting and same-name collisions are blocked with a clear error, and the post-move refresh no longer flashes the sidebar or jumps selection.

What's New

• Drag folders in the sidebar to move them into or out of subfolders.
• Drop onto All Documents to move a folder back to the library root.
• Invalid nesting and same-name collisions are blocked with a clear error.

Fixes

• Fixed a collapse/flash and temporary selection jump that could happen immediately after dropping a moved folder.
• Fixed review-feedback follow-up issues in the folder reparent flow by removing dead remap code, tightening watcher-suppression path tracking, and making animation suppression reliable.

Improvements

• Added test coverage for folder reparenting, including filesystem move validation, sidebar expanded-state preservation, and identity-registry remapping for moved subtrees (OUT-84).
