Oskar Kapala fb7828b52b supervisor: auto-cancel pending actions when drift is resolved 
When a service becomes healthy (node-agent emits service_healthy → observer
updates services.json), any previously queued redeploy/container_restart
action is stale. Without cleanup, the queue accumulates old actions that
require manual rejection.

_cancel_resolved_pending_actions() runs after each reconcile cycle:
- Reads all pending/*.json with type=redeploy or container_restart
- If the service is now healthy in actual_state, moves action to cancelled/
  with reason=drift_resolved_auto
- Only pending actions are touched; approved/running are left to the operator

Oskar Kapala 01b7758fe6 feat(node-agent): implement health monitor and safe cleanup policy 
scripts/monitor/health-monitor.sh (new):
- Standalone bash health monitor: disk/RAM/CPU checks + docker container health
- Per-node-type cleanup policy enforced:
    lte_node  (chelsty-infra, chelsty-ha): NO cleanup, no docker ops
    sd_card   (piha, saturn): dangling images + containers, rate-limited once/24h
    ai_node   (solaria): dangling + containers + build cache, NEVER -a
    standard  (vps): dangling + containers + build cache + CP filesystem rotation
- VPS filesystem rotation: completed/failed actions >7d, deploy logs >30d,
  events >3d AND past observer checkpoint
- Emits structured JSON events (node_health, disk_pressure, high_memory, high_cpu,
  containers_not_running, healthcheck_failed)

services/node-agent/ (new):
- Python daemon (node_agent.py): same policy as bash script, Docker SDK
  for container checks and cleanup, /proc for system metrics
- Optional event shipping to VPS via rsync+SSH (VPS_EVENTS_HOST env var)
- Dockerfile: python:3.11-slim + openssh-client + rsync + docker>=6.0
- docker-compose.yml: mounts docker socket, /opt/homelab, repo read-only

observer.py:
- Handle node_health: update node status + disk/mem/cpu metrics, clear disk_pressure
- Handle disk_pressure: record severity on node, clear when healthy
- Handle high_memory / high_cpu: record pressure level for correlation

supervisor.py:
- Add NO_DISK_CLEANUP_NODES = {chelsty-infra, chelsty-ha}
- reconcile() step 3: generate disk_cleanup actions for nodes with high disk pressure
- _generate_disk_cleanup_recommendation(): stable ID disk-cleanup-{node},
  checks all active states, risk=guarded (operator approval required)

executor.py:
- Handle disk_cleanup action type via _execute_disk_cleanup()
- Commands come from action payload; safety gate rejects any command touching
  /opt/homelab/data/, /opt/homelab/config/, /opt/homelab/state/, or rm -rf /

hosts/*/services.yaml:
- Rename stability-agent -> node-agent on piha, vps, solaria, chelsty-infra
- Add node-agent to chelsty-ha (previously missing)
- Add cleanup policy notes to LTE node comments

Oskar Kapala 7742bda245 feat(control-plane): add container_restart remediation 
- observer: store trigger_type on incidents for supervisor routing
- supervisor: route containers_not_running/mqtt_unreachable to container_restart instead of redeploy
- supervisor: fix node alias normalization via NODE_ALIAS_MAP
- supervisor: fix pending action dedup (scan by content not filename)
- executor: implement container_restart via SSH docker restart with retry
- control-plane override: configure NODE_ALIAS_MAP for production

oskar 9b39581b53 fix(supervisor): content-based action IDs to prevent 30s backlog accumulation 
Timestamp in reconcile-{ts}-{node}-{service} meant dedup guard never fired.
Switch to reconcile-{node}-{service} and check pending/approved/running states.
