Problem: Quit, Cmd+Q or the window's close button exited at once with
unsaved changes, leaving them to the recovery journal, so every launch
after an unsaved session offered a recovery (docs/project-files.md: no
"Save changes?" prompt on quit yet).
Fix: a close request with unsaved changes is cancelled and the existing
Save Project prompt asks Cancel / Don't Save / Save (automation ids
quit.*), as in Premiere. Don't Save discards the changes and their
recovery snapshot; Save on a never-saved project (here and in Close
Project) opens the Save dialog and returns to the prompt when cancelled.
The control channel's app.quit still quits without asking.
