Daemon Stability & Memory Audit Remediation

This release fixes a cluster of runtime reliability issues discovered during a live memory and health audit on production nodes. The most impactful changes stop a 115-second scheduler stall caused by reading a 300 MB event log on every tick (now a bounded cursor scan), close a file-descriptor leak in the delegate-runner that was trending toward EMFILE, and silence ~300 spurious “daemon degraded” phone notifications per day by replacing a naked edge trigger in the notification filter with a 180-second sustained-state hold. Also included: per-process RSS/heap OTel gauges on every daemon so future leaks can be attributed to a specific service, edge-triggered fleet-health probes that fire once per degradation episode instead of on every tick, and a health-responder backstop that now supervises the host-metrics sampler so a silently dead agent gets auto-kickstarted rather than going unnoticed for days.
