Fix

* fix(communication): Set multiprocessing start method to &39;spawn&39; and improve test synchronization

- Added a module-level setting for the multiprocessing start method to &39;spawn&39; to ensure compatibility across platforms.
- Introduced a small delay in the test for the communication channel to ensure the queue state is synchronized before assertions.

These changes enhance the reliability of the communication channel in a multiprocessing context and improve test stability. ([`1830ed4`](https://github.com/numerous-com/numerous-apps/commit/1830ed4ade76c51f0a25b23bab777625d78723b6))

* fix(communication): Improve non-blocking queue handling in QueueCommunicationChannel

- Added handling for Empty exception in receive_nowait method to prevent runtime errors when the queue is empty.
- Updated import statement to include Empty from queue module for better error management.
- Minor adjustments in test_app.py to skip multiprocessing tests during coverage runs.

These changes enhance the robustness of the communication channel by ensuring that it gracefully handles empty queue scenarios. ([`fc249d9`](https://github.com/numerous-com/numerous-apps/commit/fc249d93311702bd3e186173b98aa5bd27d8bfa6))
