Brandon ThomasandClaude Opus 5.5 590f2f67ba M3.7: auto-save + crash recovery
PRJ-7. `engine::autosave` with the session hooks the frontends call:

- Auto-save: every N minutes a dirty project is written to "EffectCraft Auto-Save" next to
  it (or a custom folder; untitled projects use the custom folder or the config dir) as
  "<name> auto-save N.ecproj", rotating through max versions (oldest overwritten, extra
  slots dropped when the maximum shrinks). Optional save when the render queue starts.
- Atomic writes for projects, auto-saves and config files: temp file + fsync + rename; a
  failed write removes the temp file and leaves the previous file intact.
- Crash recovery: a session.lock sentinel in the config dir records the open project and
  its latest auto-save; a clean exit removes it. At launch a leftover sentinel offers the
  latest auto-save in a Recover Project dialog (Settings > Startup can turn it off).
- File > Open Recent (stored in the settings) with Clear Recent Projects; Increment and
  Save uses After Effects naming ("Intro 2.ecproj"); Revert reloads the saved file.
- Commands: file.autoSave, file.recoveryInfo, file.openRecent {index|path},
  file.clearRecent.
- Tests: rotation, interval/dirty tick, simulated crash mid-write, unclean-exit detection
  and recovery, Open Recent / Increment and Save / Revert.
