Episode 16: Kuma alerts sorted by rules, a local agent and a script

ops-readonly gets kuma_alerts (host export kuma-export.py, one more read-only
mount). kuma-triage.py sorts the same data without a model. Flow H runs the
agent with skill alert-triage.md. Flow B: one open incident per monitor, an
UP closes all of them, titles name start and end and stay under Outline's
limit. B and D accept Kuma only with a header token. Monitoring notes: ntfy
rejects Kuma messages for monitors without a URL, resend for long outages.
