Adds a lightweight self-update path to the CCS Bar menu-bar app so users are
told when a newer build is available and can update with one click.
- App: BarUpdateChecker fetches the published version.txt and compares it to
the running bundle version (numeric semver). A throttled background check
(post-launch, then every 6h) surfaces an "Update available" row in the menu;
"Update Now" spawns `ccs bar install --launch --await-quit` then quits so the
installer can swap the locked bundle and relaunch. A Settings toggle gates
the auto-check (default on). Offline checks degrade silently.
- CLI: `ccs bar install --await-quit` waits for a running CCS Bar to quit
(300ms poll, 15s cap) before swapping, enabling the one-click relaunch.
- Release: bar-release publishes a machine-readable version.txt asset beside
the app zip so the check is cheap (no full download just to compare).
- Shares the ccs-binary resolver between DashboardLauncher and the updater.
- Bumps bar VERSION to 1.8.0; adds isNewer assertions to ccs-bar-check.
Closes#1588
Releasing the macOS bar app was fully manual (run package_app.sh on a Mac, then
gh release upload --clobber), so Swift-side changes never reached users until
someone remembered to rebuild and re-upload the floating ccs-bar-latest asset.
Add a tightly-scoped Bar Release workflow that does it automatically:
- triggers ONLY on push to main touching macos-bar/**, or manual dispatch, so
regular PRs, dev pushes, and non-bar changes never start it
- runs ONLY on the dedicated self-hosted macOS runner (label ccs-bar); the Linux
CI runners never match it and it never competes for them
- least-privilege contents:write, single-flight via concurrency
Version is sourced from a new macos-bar/VERSION single-line file (the workflow
reads it; the asset is always the latest build regardless). package_app.sh now
defaults to that file when no version arg is passed, so the local manual path and
CI share one source of truth. Documents the release process in docs/ccs-bar.md.
