Oskar Kapala e5ecefe2b7 feat(observer): shadow-read Prometheus up{} liveness with mismatch logging (cutover etap 1, no switching) 
Observer now optionally (PROM_SHADOW_URL) queries Prometheus up{} once per
cycle and LOGS SHADOW_LIVENESS_MISMATCH when its event-driven liveness
disagrees. Parallel-run only: compute_liveness and _emit_node_transition are
untouched; authoritative liveness stays 100% event-driven. Fail-open on any
Prometheus error (down/timeout/bad JSON -> {}). 9 new tests, incl. proof that
shadow-read does not change node_info liveness/status.

oskar 644f32d2f7 feat(hosts): add os_hostname field to all host.yaml files 
Declares the real OS-level hostname for each node so deploy-node.sh
can resolve the correct hosts/ directory without assuming
OS-hostname == logical name. Only VPS differs: its OS hostname is
ubuntu-4gb-hel1-1 while the repo directory is hosts/vps/.

- hosts/vps/services.yaml: fleet-prometheus entry (role: fleet-liveness-source,
  exposure: tailscale-internal, port 9090, runtime paths, depends_on node_exporter)
- inventory/topology.yaml: add fleet-prometheus to the vps services list

oskar c1f4172340 docs(hosts/vps): notatka host-state — /swapfile 4G + swappiness=10 
Celowy stan host-level (poza GitOps) udokumentowany w manifescie, zeby przy
odtwarzaniu VPS nie zniknal cicho. Tylko opisowy blok host_state, bez zmian
struktury runtime/deploy.

Oskar Kapala 267742c7d7 vps/node-agent: add network_mode: host for control-plane health probe 
The _check_control_plane_health() method probes localhost:18180, which
is the control-plane's mapped port. Inside a bridged container, localhost
resolves to the container's own loopback — the probe always fails.

host network mode shares the VPS host's network namespace so that
localhost:18180 correctly reaches the control-plane.

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
