MAESTRO: Document and test file deletion handling in Document Graph
Added comprehensive tests documenting how file deletions are handled: - File watcher captures 'unlink' events and batches within 500ms debounce - Graph rebuild excludes deleted files (no node created) - Edges to/from deleted nodes are automatically removed (buildGraphData only creates edges for files that exist) - diffNodes identifies removed nodes for exit animation - Position preservation works for remaining nodes after deletion - External link nodes removed when all referencing docs deleted - Multiple simultaneous deletions (folder delete) handled via batching The file deletion feature was already fully implemented; these tests document the expected behavior and edge cases for maintainability.

/**
|

* File Deletion Handling Tests
|
||||
*
|
||||
* When a markdown file is deleted, the Document Graph must:
|
||||
* 1. Detect the deletion via chokidar 'unlink' event
|
||||
* 2. Batch the event with any other changes (500ms debounce)
|
||||
* 3. Send the event to the renderer
|
||||
* 4. Trigger a graph rebuild which excludes the deleted file
|
||||
* 5. Animate the deleted node exiting
|
||||
* 6. Remove all edges connected to the deleted node
|
||||
*
|
||||
* The edges are removed automatically because:
|
||||
* - The graph rebuild re-scans the directory (deleted file not included)
|
||||
* - buildGraphData only creates edges for files that exist
|
||||
* - The new edge set excludes edges to/from the deleted file
|
||||
* - setEdges() replaces all edges with the new set
