New securityRegistry (separate from companionRegistry) with two read-only,
secret-free tools for the Yerin security agent:
- audit_log: query the redacted audit trail by actor_kind/actor_id
- agent_inventory: list agents + capabilities/scopes (explicit projection,
never SELECT *, no token material)
Follows the existing createRegistry() pattern. Design + wiring roadmap in
docs/yerin-security-agent.md. Not yet seeded/exposed over MCP (left for review).
