Ensure prompt.insertText, attachments.insertFileReference, and
attachments.removeFileReference move the cursor to the correct
position after modifying the prompt editor. Previously the cursor
stayed at the start of inserted text, which broke the natural
flow for plugin-driven file attachments like screenshot-paste.
- WorkspaceFiles: writeFile, deleteFile, moveFile with path safety
- writeFile: text/binary, auto-create dirs, overwrite option
- deleteFile: idempotent, uses lstat (removes symlinks not targets)
- moveFile: unix mv semantics, overwrite defaults to false
- All mutations auto-refreshFiles() in File Explorer
- Symlink escape prevention via realpath(dirname) check
- PluginPromptEditor: insertText, getText, getSelection, onPaste, onKeyDown, focus
- Uses CM6 EditorView.domEventHandlers() via Compartment (not raw DOM)
- Handlers registered before mount are preserved and applied on mount
- First-to-consume-wins ordering for multi-plugin scenarios
- insertText replaces selection (not inserts after)
- PluginAttachments: insertFileReference, getAttachedFiles, removeFileReference
- insertFileReference validates file exists before inserting @path
- Does not auto-focus editor (unlike prompt.insertText)
- @file regex requires file extension to avoid matching emails
- Server endpoints: PUT /file, DELETE /file, POST /file/move
- All work for local and federated machines
- Tests: 31 unit tests, 9 integration tests, 5 client tests
- Docs: 3 new sections in plugins.md
