The G522 uses a Centurion protocol variant with report ID 0x50 that adds
a device address byte at frame position [1], shifting all CPL fields by
+1 compared to the PRO X 2's 0x51 variant. This commit adds transport-
layer support for both variants while consolidating per-handle centurion
state into a single CenturionHandleState dataclass.
Key changes:
- Consolidate _centurion_handles (set) and _centurion_protocol_versions
(dict) into a single dict[int, CenturionHandleState] keyed by handle
- Add _unwrap_centurion_frame() helper that auto-detects 0x50 vs 0x51
from raw frame bytes and learns the device address on first RX
- Add _centurion_frame_header() to build the correct TX header per variant
- Detect both report IDs in udev report descriptor parsing
- Adjust bridge fragment chunk sizes for 0x50's extra header byte
- Propagate full CenturionHandleState when opening per-thread handles
Wire format verified against G522 diagnostic logs from LGSTrayEx#15.
