feat: Improve Mycelium Streamer functionality

- Added continuous data writing and verification to the master node
  to ensure data persistence and integrity.
- Simplified worker update handling in the `listen` function for
  better efficiency and error handling.  The previous implementation
  had unnecessary complexity and potential for hangs.
