Startup auto-update retried the same cached target on every launch after a failure, which could strand users before the TUI started. This adds a same-version cooldown, skips opportunistic auto-update for `--resume`, and terminates updater process groups on timeout so stale children do not hold locks. Focused unit coverage was added for the cooldown, resume gating, and timeout cleanup paths.
