Document the BZM2 thread and protocol error surface more clearly, centralize hex formatting usage, and clean up several thread internals that were carrying avoidable complexity. This keeps the actor-based hashing path easier to follow while preserving the existing behavior and test coverage.

Converting the PR to a draft as the BIRDS is just being used for testing and review. When ready, the bitaxeBonanza+bitaxe raw will replace the BIRDS board and at that time this PR should be ready for full review. The bzm2 and nine_bit modules, are ready to be reviewed. |

This PR adds end-to-end BIRDS/BZM2 support to mujina-miner.
It introduces the BIRDS board implementation and BZM2 protocol stack, including 9-bit serial transport, protocol encoding/decoding, chip bring-up, WRITEJOB support, task dispatch, READRESULT mapping, and share validation. It also wires BIRDS into the board inventory/registration path, initializes the BIRDS data port over BZM2, and creates the BZM2 hash thread.
The hash thread makes use of bring-up, hashing, work, and tracking modules to make the thread module a bit more maintainable.
Fan, Voltage regulator, and dynamic frequency adjustments are not currently implemented.
To test this out, you need a bitaxeBIRDS board, the voltage regulator needs to be set properly with an initialization script (https://github.com/skot/bzm-raw-py/blob/birds/vr-bringup.py), and your the pico on the birds device needs the appropriate firmware.
