Resolved rebase conflicts, fixed build errors across pkg/tools and pkg/providers, and fully integrated the Agent Shield security suite (Canary, PII, IPIA, Policy, Behavior).
Key stabilization:
- Fixed filesystem tool constructor signatures and tests.
- Re-implemented timing-safe authentication in health/server.go.
- Synchronized gateway and channel manager initialization.
- Cleaned up architecture leakage and deprecated endpoints (/cgat).
- Removed local/sensitive paths from logs and .dockerignore.
