Agent Skills: system-health-responder

End-of-action reflex that reads the system-health contract, engage-locks, Eisenhower-ranks the warnings, does MODERATE non-destructive auto-heal (autonomous reversible renice of a clear cpu runaway + `uv cache prune` producer-hygiene), responds to the new `agentic_tools` branch (`claude doctor` runtime health + cache-producer pressure), reads the reclaim-aware `burn_down` disk forecast (observe-only leading indicator → seed+notify before crisis), and escalate-seeds the HITL residue (security · malware · kill · disk→disk-guardian · no-source-fix offender containment). EKO-90 part-2 — the responder half of the health suite.
