Claude/remove persona system f vgt m (#126)

* Remove persona system, identity, and all Timmy references

Strip the codebase to pure orchestration logic:

- Delete TIMMY_IDENTITY.md and memory/self/identity.md
- Gut brain/identity.py to no-op stubs (empty returns)
- Remove all system prompts reinforcing Timmy's character, faith,
  sovereignty, sign-off ("Sir, affirmative"), and agent roster
- Replace identity-laden prompts with generic local-AI-assistant prompts
- Remove "You work for Timmy" from all sub-agent system prompts
- Rename PersonaTools → AgentTools, PERSONA_TOOLKITS → AGENT_TOOLKITS
- Replace "timmy" agent ID with "orchestrator" across routes, marketplace,
  tools catalog, and orchestrator class
- Strip Timmy references from config comments, templates, telegram bot,
  chat API, and dashboard UI
- Delete tests/brain/test_identity.py entirely
- Fix all test assertions that checked for persona identity content

729 tests pass (2 pre-existing failures in test_calm.py unrelated).

* Add Taskosaur (PM + AI task execution) to docker-compose

Spins up Taskosaur alongside the dashboard on `docker compose up`:
- postgres:16-alpine (port 5432, Taskosaur DB)
- redis:7-alpine (Bull queue backend)
- taskosaur (ports 3000 API / 3001 UI)
- dashboard now depends_on taskosaur healthy
- TASKOSAUR_API_URL injected into dashboard environment

Dashboard can reach Taskosaur at http://taskosaur:3000/api on the
internal network. Frontend UI accessible at http://localhost:3001.
