fix: move ThrmlSeismicBridge to quantum_swarm_blockchain_bridge.py

- Merges the ThrmlSeismicBridge class into an existing file that successfully handles JAX imports and CI builds
- Removes the separate seismic_bridge.py file to avoid build system conflicts
- Maintains optional JAX support for worker compatibility
