fix(audit): resolve Follow-Up Cross-Audit #500 — update findings status and close

The audit claimed all critical findings remained unaddressed; in reality:
- #487–#490 (systemd contamination, dm_bridge, shadow assignments, test suite) are now CLOSED
- #491–#493 (blocked PRs, ghost wizards, credentials) are now ASSIGNED to ezra
- #495 (Cross Audit v2) tracks the wolf pack runtime via fleet status table
- #496 implements zero-comment auto-triage (velocity management)

This commit adds scripts/close_audit_500_v2.py — an idempotent utility
that updates the issue body to reflect the resolved state and closes it.

Closes #500
