Add WHOOSH search service with BACKBEAT integration

Complete implementation:
- Go-based search service with PostgreSQL and Redis backend
- BACKBEAT SDK integration for beat-aware search operations
- Docker containerization with multi-stage builds
- Comprehensive API endpoints for project analysis and search
- Database migrations and schema management
- GITEA integration for repository management
- Team composition analysis and recommendations

Key features:
- Beat-synchronized search operations with timing coordination
- Phase-based operation tracking (started → querying → ranking → completed)
- Docker Swarm deployment configuration
- Health checks and monitoring
- Secure configuration with environment variables

Architecture:
- Microservice design with clean API boundaries
- Background processing for long-running analysis
- Modular internal structure with proper separation of concerns
- Integration with CHORUS ecosystem via BACKBEAT timing
