Two separate causes of stationary trigger pulsing, both fixed:
1. Hysteresis too short. 30 packets (0.5s) was shorter than FH5's
stationary oscillation period (~1s per state in start-grid/pause
screen contexts). Bumped to 120 (2s at 60Hz).
2. RPM-stuck workaround removed entirely. Cosmii's RPM_ACCUMULATOR
(legacy_Program.cs:89-109) forced is_race_on false after 3.3s of
constant RPM + zero power. While stationary in-race (idle RPM
constant, power near zero), this would trip, causing a false
menu transition. Engine idle flutter on power could reset and
re-trigger it, producing a slow oscillation with clicks on each
edge. FH5 has been observed to correctly clear is_race_on between
races (confirmed via live strace), so the workaround is unnecessary.
Removed: RPM_ACCUMULATOR_TRIGGER_RACE_OFF constant, is_race_on's
debounce logic, DaemonState.last_rpm and .rpm_accumulator fields.
is_race_on is now a one-liner: return bool(is_race_on field).
Tests: 57/57 pass. TestIsRaceOn simplified from 4 to 3 tests.
DaemonState reset test no longer checks removed fields.
