- Coalescing queue: use HasPendingTaskForIssue (queued/dispatched only) instead of HasActiveTaskForIssue so comments during a running task enqueue exactly one follow-up task that picks up all new comments. - Stale task cleanup: runtime sweeper now fails orphaned tasks when their runtime goes offline (daemon crash/network partition). - Cancel-aware daemon: handleTask checks task status after execution and discards results if the task was cancelled mid-run (e.g. reassign). - Terminal issue guard: ClaimTaskForRuntime auto-cancels pending tasks for done/cancelled issues instead of executing them. - Race condition safety net: unique partial index ensures at most one pending task per issue at the DB level.
