Fix concurrent daemon startup race condition

backnotprop · backnotprop · commit 1048daf388e7 · 2026-05-17T18:27:41.000-07:00
When two CLI processes race to start a daemon, the loser's child exits
after failing to acquire the lock. Previously ensureDaemonClient gave up
immediately on child exit. Now it continues polling for ~1s to discover
the winning daemon before failing.
