Summary

When a .flyde file is imported by other flows and then moved to a different folder, the import path breaks. This fix adds a onDidRenameFiles listener that automatically updates all import references when .flyde files are moved or renamed.

Changes

• NEW vscode/src/updateImportsOnFileMove.ts — listens for file rename events, finds all .flyde files that reference the moved file, updates the import paths
• MODIFIED vscode/src/extension.ts — registers the updateImportsOnFileMove handler

How to Test

1. Create a .flyde flow that imports another .flyde file
2. Move the imported file to a different folder
3. The import path in the parent flow should automatically update
