bvandeusenandClaude Opus 5.5 56063f27a4 fix(docker): a container's memory is its processes' own; file cache shown on its page (#6030)

The agent sent Docker's working set (usage less inactive_file), which still
counts recently used file cache. A file-heavy container with no limit read
191 GB while its processes held 2.2 GB, and the host's own figure, which
already leaves cache out, disagreed with it.

Agent 1.23.0 sends mem_used_bytes / mem_used_pct (anon + shmem, so
Postgres's shared buffers count; v1: rss + shmem) and mem_cache_bytes
apart. The new names keep the two meanings apart in history and in learned
normals: docker_013 renames the columns, clears the old values and adds
mem_cache_bytes. The Docker page, swarm by-node sums, Busiest Containers,
container detail, normals and the MCP tools all read the new figure. File
cache is shown only on the container's page and in get_container.

bvandeusenandClaude Opus 5.5 e9341c5639 feat(docker): overview findings say when the problem began
#5013 "Overview findings for containers and Swarm services carry since=null"

- Container problems are dated from their own evidence: a crash or restart
  loop from its first death in the hour, an OOM kill or error exit from the
  death that ended it, a failing healthcheck from its last turn to unhealthy.
  list_containers and get_container carry problem_since / problem_age_s.
- Swarm services carry trouble_since: a crash loop's first failure in the
  hour, a short service's oldest troubled task in each failing slot, a
  recovered service's first failure in 24h. list_swarm_services shows it.
- get_overview findings from the docker plugin now have since and age_s,
  so they rank by how long they have stood.

bvandeusenandClaude Opus 5.5 bac2859455 feat(docker): Swarm task awareness — replaced tasks, service crash loops, last task error
CI / lint (push) Successful in 3s
CI / integration (push) Successful in 52s
CI / unit (push) Successful in 1m10s
CI / publish (push) Successful in 1m41s
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.

bvandeusenandClaude Opus 4.8 24df8458ea feat(docker): swarm-aware container views — collapse replicas, show host, surface agent-less tasks
CI / lint (push) Successful in 2s
CI / integration (push) Successful in 2m19s
CI / publish (push) Successful in 1m3s
CI / unit (push) Successful in 45s
The container list and dashboard widget listed each swarm task as its own cryptic
row (svc.1.<taskid>) and could only show tasks on nodes that run a Steward agent.
Make both views service-centric and cluster-complete.

- swarm_view.build_swarm_services(): model-free builder that merges real container
  rows (collected local-per-node, so host_id = the node a task runs on) with the
  managers' placement (DockerSwarmService.placement_json). Where placement counts
  exceed the local rows on a node — i.e. nodes with no agent — it synthesizes
  "ghost" replicas so the replica list matches the cluster. Non-swarm containers
  pass through grouped by host.
- /rows + rows.html: a Swarm-services panel collapses each service to one block,
  every replica a host chip (status + cpu); ghosts render dashed "N · no agent".
  Non-swarm/compose containers keep the per-host table below. New Services stat.
- /widget + widget.html: same service collapse with host chips; standalone
  containers stay grouped by host.
- Unit tests for the builder (real+ghost merge, full coverage, partial agent-less,
  synthesized service, down state).

No migration — node_id, placement_json and swarm-node hostnames are already stored.
