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.

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.

- 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
