* Show update-available banner automatically on launch
Probe for updates immediately on launch via Sparkle's
checkForUpdateInformation() so the sidebar surfaces a passive update
indicator without waiting for the 24h scheduler. When Sparkle detects
an available update in the background, the pill now shows
"Update Available: X.Y.Z" with accent styling while the updater is
idle. Clicking it triggers the full interactive update flow.
Also fixes thread safety in delegate callbacks by dispatching
@Published mutations to the main queue.
Closes#1643

* Add periodic background update probe every 15 minutes
The launch-only probe wouldn't catch updates published while the app
is already running. Add a repeating 15-minute timer that calls
checkForUpdateInformation() so the sidebar banner appears within a
reasonable window after a new version is published.

* Change background update probe interval to 30 minutes

* Change update check interval to 1 hour and migrate existing users
Reduce Sparkle's scheduled check interval from 24h to 1h so update
banners appear sooner. Migrate users stuck on the old 24h default by
bumping the migration key to v2. Align background probe interval with
the Sparkle check interval instead of hardcoding 30 minutes.

The nightly build is now a distinct app called "cmux NIGHTLY" with
bundle ID com.cmuxterm.app.nightly, allowing side-by-side installation
with the stable release. The nightly appcast URL is baked into the
app's Info.plist by CI, so no in-app channel switching is needed.
- Nightly workflow: rename app to "cmux NIGHTLY", set bundle ID to
com.cmuxterm.app.nightly, hardcode nightly Sparkle feed URL, publish
DMG as cmux-nightly-macos.dmg
- Remove "Receive Nightly Builds" toggle from settings
- Remove UpdateChannelSettings enum and simplify feed URL resolution
to just use SUFeedURL from Info.plist
- Remove UpdateChannelSettingsTests (no longer applicable)
After a Sparkle auto-update relaunches cmux, the control socket stops
accepting connections because start() early-returns when isRunning is
true, without checking if the accept loop thread is actually alive.
- Add acceptLoopAlive flag to track accept loop thread liveness
- Fix start() early-return to also check acceptLoopAlive, so a dead
thread triggers full socket re-creation
- Break acceptLoop() after 50 consecutive accept() failures with 10ms
backoff instead of tight-spinning forever
- Clean up socket in applicationWillTerminate and
updaterWillRelaunchApplication for clean teardown before relaunch
