- Moved 3 actively-used custom agent modules to timmy-config/extensions/
- shield.py (crisis & jailbreak detection)
- privacy_filter.py (PII stripping for remote API calls)
- smart_model_routing.py (cheap vs strong model heuristic)
- Updated deploy.sh to copy extensions/ to ~/.hermes/agent/
- Added comprehensive migration doc in docs/AGENT_EXTENSION_MIGRATION.md
- Archived 16 dead/unused agent/*.py modules to agent/archive/ in hermes-agent
This is SIDECAR-3 — restructure agent/* extensions as sidecar skills.
