Two issues in the deployed daemon:
1. After FH5 exits, the lightbar stayed lit. reset_triggers() touched
only triggers; pydualsense's BG sendReport thread kept re-publishing
whatever TouchpadColor we last set, so the controller stayed in the
last race color forever.
2. R2 had residual tension in FH5's main menu and on the desktop after
a race. Pre-race / idle states were emitting RacingDSX's NormalTrigger
(mode byte 0x00), which per Sony's docs (Nielk1 Rev6) only clears
state without retracting the trigger motor; mode 0x05 (canonical Off
/ Reset) actively returns the trigger to neutral. RacingDSX-on-Windows
gets away with 0x00 because something else (Steam Input or the OS)
reliably resets the motor on focus loss; on Linux nothing does.
Fixes:
- Drop _apply_normal/DS_MODE_NORMAL. Use _apply_off (mode 0x05) for every
'release the trigger' intent: pre-race per-frame, idle timeout, mid-race
zero-strength fallback, shutdown.
- Add reset_lightbar() that writes RGB(0,0,0).
- Track have_telemetry and fire the idle-timeout branch whenever
telemetry has been silent for IDLE_TIMEOUT_S, regardless of in_race.
Reset both triggers and lightbar in that branch.
Documented as divergence #4 in the module docstring.
