joakim ba0cfc08e3 feat: Phase 1 - Core API server with authentication
- Added database schema for users, api_keys, sync_state, change_log, and sync_config
- Implemented API key generation and validation with bcrypt hashing
- Created Chi-based REST API server with endpoints for:
  - Task CRUD operations (create, read, update, delete)
  - Task actions (complete, start, stop)
  - Tag management (list, add, remove)
  - Projects listing
  - Health check endpoint
- Added middleware for authentication and CORS
- Implemented change log tracking with triggers (key:value format)
- Added configurable change log retention (default 30 days)
- Created server CLI commands (opal server start, opal server keygen)
- Dependencies added: golang.org/x/crypto/bcrypt, github.com/go-chi/chi/v5
