kuhy: "I do not want it to work like this, I want it to just work
normally." PS4 mode (046D:C260) cannot be supported on this PC (no kernel
driver, SDL lg4ff has no c260 either, so FFB is dead there too) and the
selector is physical. Keep the mode detection so the journal and --status
name PS4 mode instead of "not found"; drop the desktop notification and
the 5-minute Restart loop.

On the 2026-09-15 and 2026-09-17 boots the wheel enumerated as 046D:C260
(PS3/PS4 selector in PS4 position, bound by hid-generic). The BPF udev
rule, the ensure unit and its hotplug rule all keyed on C24F, so the unit
failed once with "no G29 found" and nothing was said; 1st/3rd stayed on
the firmware's bad decode until the selector was flipped a day later.
- fixes/g29_wheel_mode.sh (new, sourced): classify the HID bus as
native/ps4/compat/absent; root-safe desktop notification via
/run/user/*/bus + sudo -u.
- --ensure: absent -> exit 0; ps4/compat -> exit 1 + critical
notification; native -> attach. --status prints the mode first.
- g29-shifter-bpf.service: Restart=on-failure, RestartSec=5min so a
notification lost before the session bus exists at boot is re-sent.
- 99-g29-shifter-ensure.rules: also fires on C260.
- tests/test_fix_g29_shifter.bats: 13 tests against a fake sysfs tree.
