Milestone 465 "Swarm task awareness". Fixes three defects from the live MCP review #4973: - #5008 "Swarm task history read as live state" - #5009 "Crash-loop detection is blind to Swarm services" - #5011 "Swarm task errors are not captured" Agent and ingest (agent 1.8.0): - A manager's agent now reports each service's newest tasks: slot, node, desired and current state, Swarm's Err/Message, exit code and time. - They are stored in docker_swarm_services.tasks_json (migration docker_010_swarm_tasks). Swarm view (pure): - A task container is "replaced" when Swarm set its task's desired state off `running`. Without the task on record, a newer or running task in the same slot decides. - Replaced containers are no longer replicas or crashes. - Each service gets, from the task records: - failures_1h and failures_24h (failed or rejected tasks); - crash_looping (Settings → Thresholds count); - last_error, in Swarm's own words. MCP: - New findings: swarm_service_crash_looping (critical) and swarm_task_failed (warning, on a healthy service with a failure in 24h). - Down and degraded findings name the last task error. - list_swarm_services carries the failure fields. - Container rows mark swarm_replaced and give a replaced task no problems. Web: - The containers page swarm cards and the Swarm topology page show crash loops, recent failures and the last task error. - The dashboard widget flags a crash loop, and its "failed (24h)" count no longer counts a rolling update's killed task.

"""Docker swarm service tasks column

|
Adds docker_swarm_services.tasks_json — each service's newest tasks as a
|
|
manager's agent (≥ 1.8.0) reports them: slot, node, desired and current state,
|
|
Swarm's error and message, exit code and time. Lets Steward tell a task Swarm
|
|
replaced from one that crashed, count a service's failures across task
|
|
retries, and say why its last task failed. Additive column; no DROP+recreate.
