Claude 2d393c601b Add Docker Swarm verification checks and diagnostics ...

This commit enhances the Docker diagnostics system with comprehensive
Swarm-specific health checks to ensure the application is properly
deployed in a Docker Swarm/CapRover environment.

Changes:
- Add check_swarm_status() function to verify Docker Swarm configuration
  - Checks if Docker is running in Swarm mode
  - Retrieves and logs Swarm node information (hostname, role, state)
  - Detects if container is running as a Swarm service task
  - Provides clear diagnostic messages for troubleshooting

- Integrate Swarm checks into application startup (app.py)
  - Runs after Docker connection is verified
  - Logs success for production Swarm deployments
  - Warns (but doesn't fail) for local development environments

- Add comprehensive test coverage (8 new tests)
  - Tests for active/inactive Swarm states
  - Tests for error handling and edge cases
  - Tests for node retrieval and hostname detection
  - Maintains 99% overall code coverage (128 tests passing)

This ensures that Docker Swarm-related issues are caught early during
deployment and provides clear diagnostic information for troubleshooting
CapRover deployments with Docker socket mounting.
