Initial: Fastify API + DB schema + collab setup

- Fastify API on :3000 (tasks, groups, auth, connectors)
- PostgreSQL schema: users, tasks, task_groups, goals, connectors
- 8 default task groups
- JWT auth (register/login/me)
- API Bridge framework with webhooks
- CLAUDE.md + polling scripts
- Collab worker integration
