v1.4.0

Added

• Slow job webhook alert — set alert_slow_job_count_threshold (integer) to fire a webhook whenever the number of currently-running slow jobs meets or exceeds the configured count; requires slow_job_threshold to define what "slow" means; uses the same alert_webhook_url and alert_webhook_cooldown settings as other alert types; event name slow_job_threshold_exceeded
• Stale process webhook alert — set alert_stale_process_threshold (integer) to fire a webhook whenever the number of stale workers meets or exceeds the configured count; a process is stale when its heartbeat has not been updated within SolidQueue.process_alive_threshold; uses the same alert_webhook_url and alert_webhook_cooldown settings; event name stale_process_detected
• Job wait time column — the Running tab now shows a "Wait Time" column displaying how long each claimed job waited in the queue from enqueue to pickup; also included as wait_time_seconds in the CSV export for the claimed status
• Eliminate N+1 queries on the queues index — queue.size and queue.paused? previously fired one query each per queue; both are now pre-computed in the controller with single batch aggregations (GROUP BY queue_name for sizes, one Pause query for paused state), reducing query count from O(2N+constant) to O(constant) regardless of queue count
