feat: improve LSP lifecycle, terminal widget, and code folding support
- LSP:
- Add shutdown and exit request/notification handling
- Send initialized notification after initialize response
- Gracefully close clients with delayed shutdown via GLib timeout
- Fix LSP WS server ↔ Godot LSP communication flow
- Terminal (VteWidget):

- Improve UX: scrollback, no audible bell, auto scroll
- Implement clipboard shortcuts, selection copy, middle-click paste
- Track cwd changes and update UI label
- Add proper signal wiring and cleanup on destroy
- Code folding:
- Add fold support for JS, HTML, CSS, JSON, C, C++, Go
- Reset fold state safely when AST or filetype is unavailable
- UI (Plugins dialog):
- Improve dialog behavior (non-modal, centered, transient)
- Add focus-out auto-hide and Ctrl+Shift+P shortcut
- Misc:
- Add type hints in VTE widget
