Verified against a real Kuma by stopping it mid-test:
- get_monitors() reads the library's CACHED monitorList event, so it reported
'up' long after Kuma died. Reachability now does a real HTTP round-trip plus a
live socket check.
- the cached list could yield an id for a monitor that no longer exists; a match
is now confirmed with a live get_monitor before it is returned, so CluPilot can
never record a target that is never checked.
- liveness (/health, always 200 while serving) split from readiness (/ready, 503
when Kuma is unreachable) — the container healthcheck must not restart a
healthy bridge just because a dependency is down.
