Resolve all 374 ruff errors across 36 Python files (E501, E702, E722,
E741, F821, F841, invalid-syntax) bringing `ruff check .` to zero
errors repo-wide with line-length=100.
Rewrite CI workflow to use uv for dependency management, whole-repo
`ruff check .`, py_compile syntax gate, and merged python-tests job.
Add pyproject.toml with ruff config and uv dependency groups.
CI structure proposed by hcm444.
Remove unused imports (deque, sys, Opcode, struct, _REPLAY_ADJUSTABLE_OPCODES)
across 4 active Python files and refactor semicolons to separate statements
in radar_protocol.py. Add ruff lint job to CI workflow targeting only the
active files (excludes legacy GUI_V*.py and v7/).
Align test suite with FT601 removal from radar_protocol.py:
- Replace FT601Connection with FT2232HConnection throughout
- Rewrite _make_data_packet() to build 11-byte packets (was 35-byte)
- Update data packet roundtrip test for 11-byte format
- Fix truncation test threshold (20 -> 6 bytes, since packets are 11)
- Update ReplayConnection frame_len assertions (35 -> 11 per packet)
57 passed, 1 skipped (h5py), 0 failed.
