foxyzandClaude Opus 5.5 beae87b0cc Updater: real-layout apply with rollback, in-app update + restart
- Strip the tarball's top-level folder; stage inside the install root
  (same filesystem) and swap with full rollback; keep file modes.
- Semver prerelease ordering (1.2.3-rc1 < 1.2.3).
- UpdateController: background check, download with progress, apply,
  restart; required-update wording for newer protocols; Check now.
- update.sh/update.bat in the bundle; Windows apply path (untested).
