Implement initial scan logic and council formation for WHOOSH project kickoffs

- Replace incremental sync with full scan for new repositories
- Add initial_scan status to bypass Since parameter filtering
- Implement council formation detection for Design Brief issues
- Add version display to WHOOSH UI header for debugging
- Fix Docker token authentication with trailing newline removal
- Add comprehensive council orchestration with Docker Swarm integration
- Include BACKBEAT prototype integration for distributed timing
- Support council-specific agent roles and deployment strategies
- Transition repositories to active status after content discovery

Key architectural improvements:
- Full scan approach for new project detection vs incremental sync
- Council formation triggered by chorus-entrypoint labeled Design Briefs
- Proper token handling and authentication for Gitea API calls
- Support for both initial discovery and ongoing task monitoring

This enables autonomous project kickoff workflows where Design Brief issues
automatically trigger formation of specialized agent councils for new projects.
