gsxdsm af06170a51 FN-6778: add agent artifact registry tools ...

Adds engine and chat tools for registering, discovering, and viewing artifacts with inbox notifications.

- Add fn_artifact_register, fn_artifact_list, and fn_artifact_view tools for heartbeat, executor, and chat sessions.
- Send best-effort dashboard system inbox notifications when artifacts are registered.
- Classify artifact tools for action gating and coordination exemptions, with coverage for executor, heartbeat, permanent agent, and chat flows.
- Document the artifact registry behavior and update package metadata, quarantine ledger, and line-count baseline.
