M3.9: closing a modified project asks to save it first; the modified mark follows undo

- Quit and the window's close button, File ▸ New Project, Open Project, Open Recent, Close
  Project, the demo project and a Home template show Save / Don't Save / Cancel when the
  project has unsaved changes (Save asks for a path when untitled; cancelling that keeps the
  project open). File ▸ Revert asks to discard. Before, all of them dropped unsaved work
  without asking.
- The window title shows the project's path and `*` while it is modified.
- The modified mark follows undo: the session keeps the snapshot it last opened or saved
  (`Session::saved_project`), so undoing, jumping in the History panel or rolling back a batch
  to the saved state clears it.
- An edit that changes nothing (a value set to what it already is) records no undo step and
  doesn't mark the project modified (`Project::same_content`, comparing untouched comps by
  pointer).
- Agents' `engine.execute` / MCP calls are never asked; `ui.menu.invoke` shows the prompt like a
  click (automation ids `dialog.unsaved.save` / `dontSave` / `revert` / `cancel`), and the
  control channel's `app.quit {force: true}` skips it.
- Docs: architecture, agents, control protocol, parity.
