Update Codeman from the web UI: a "Check for updates" button queries GitHub
for the latest tagged release (git ls-remote fallback) and shows release
notes; "Update now" runs git checkout <tag> → npm install → npm run build →
restart, streaming live progress that survives the service restart.
- Release-tag channel; dirty trees auto-stashed (left for manual git stash pop)
- Cross-platform restart: systemd / launchd / manual, detected at runtime
- Updater runs detached (systemd-run --scope on Linux, setsid on macOS) so the
restart it triggers can't kill the build mid-flight
- Build-failure rollback to the pre-update commit; boot reconcile with an
update-id/freshness guard; 409 concurrency lock; runner staged outside the
repo; strict tag validation; CODEMAN_DISABLE_SELF_UPDATE kill-switch
- Endpoints: GET /api/system/update/check, POST /api/system/update,
GET /api/system/update/status
