feat: real release notes, restart button, reliable .run installer (0.0.10)

- feat(ci): set each Gitea release body from the matching CHANGELOG section
  (was hardcoded "Automated release for…")
- feat(updater): show "What's new" — release notes dialog before applying (GUI)
  and in `rigdoctor update` (CLI); fetch_latest/update_state now return notes
- feat(gui): "Restart now" button relaunches the app after an update is applied
- fix(packaging): build the self-extracting .run with a pure-Python extractor
  (packaging/make_run.py) instead of makeself, so it attaches to every release
  (it was silently skipped before)
- chore: adopt Conventional Commits + git-cliff (cliff.toml, packaging/
  changelog.sh) for changelog generation going forward (D20)
- chore(gui): drop internal module refs (M4, M5, …) from Setup descriptions
