NEON-29: Latch stable idle on ridged stair treads (idle jitter). 

Idle jitter was not walk/peel: without has_goal, stable idle required
floor_normal·up >= 0.998. Tread+riser contacts often report ~0.996–0.997,
so stable idle never latched and rim settle nudge + idle move_and_slide
ran every tick. Use STABLE_IDLE_FLOOR_HOLD_MIN_UP_DOT (0.992) for the
floor-flat check when slide contacts are ridged and we are still using the
strict entry threshold.
