Continuum: Claude, Codex, Grok

# Continuum 0.72.0 Follow-up to 0.71.0's sync work: your Mac stays reachable on its own, and the phone finally shows the truth about what's running. ## What's new - **Your Mac heals itself instead of going dark.** After a crash-relaunch or a stale enrollment, the Mac could get stuck "offline" forever — no restart or re-sign-in brought it back. It now detects the stall, clears the bad enrollment, and re-enrolls itself automatically. (#1352) - **PR controls on your phone finally know what state you're in.** Instead of a permanent orange **Create PR** button — which stayed loud after the work was done and offered to open a second PR against an already-merged branch — iOS and Android now show the same three-state control the Mac has: *Create PR* when there isn't one, a colour-coded PR pill when there is, and a *Merge* button when checks are green. (#1367) - **Usage gauges work again on iPhone.** They were pinned at 0% with a recurring "Your Mac didn't respond in time" — the phone was asking the wrong machine. It now reads usage from a live Mac, and holds the last good numbers through a relay blip instead of flickering every five seconds. (#1365, #1366) - **Live sessions actually look live.** A session running on another device showed as finished — no data-stream animation, no "Live on another device". Running sessions now report their real status across every client. (#1365, #1366) ## Under the hood - Host-control startup gets a 30-second watchdog and retries on the mirror timer, so a single failed enroll can no longer strand a machine. (#1352) - Sessions resumed after an app restart re-attach their event wiring, so the session registry stops publishing a frozen row. (#1366) - PR-state vocabulary moved into one shared model (Swift + TypeScript) with matching tests, so the Mac, iOS, and Expo clients can't drift apart on what a merged PR looks like. (#1367)
