Krzysztof kuhy Rudnicki 7e2d78c7db Add the G29 shifter HID-BPF fix (1st/3rd engage reliably)
Live on this host since 2026-09-11 but never committed. The wheel firmware
decodes the shifter's hall sensor itself and this unit's top row rests at
Y 180-193, below the ~195 engage threshold, so 1st/3rd often did not
register. g29_shifter.bpf.c re-decodes those two gates from the raw X/Y
bytes with hysteresis (engage >= 160, release <= 140) and ORs the bit in
before hid-logitech parses the report; it never clears a bit, so the
firmware's working gates cannot regress. fix_g29_shifter.sh builds,
attaches and installs it persistently (udev-hid-bpf rule + a systemd
safety-net unit pulled in on every re-enumeration); g29_shifter_capture.py
records and grades raw captures per gate.

Two files were over the 250-line cap: the test file is split at the
record/CLI boundary with the report builders moved into a conftest fixture
(the naming hook allows only test_*.py in tests/), and the grader's
docstrings are tightened. No behaviour change to the installed fix.
