release(v4.8.5): bump framework and eight skills to 4.8.5 in lockstep

Issue #45 A+B: MAM's isolated herdr servers start with restore-on-restart off,
and resume closes the session's own restored empty shell. Not reviewed yet.

 name: multi-agent-mux-monitor
 description: "Run a long-lived reconciler that watches .mam/agent-sessions.yaml against the actual herdr/agent runtime state and reconciles them. Use when you want live visibility into which agent sessions are running, which are dead, which have stale YAML entries, and which have new session ids that haven't been recorded yet. Runs as a persistent loop (`reconcile.sh --subscribe`) that keeps going until it times out, idles out, or is interrupted."
