Joe DiPrimaandClaude Opus 5 fcd1a0ca8d #142 crouch: refuse-and-snap, not queue -- and honour the must-be-stopped rule
Fixes a regression I introduced in 59f53da.  That revision retried the request
when the posture gate was not ready, which is worse than the drop it replaced:
benched, a crouch tapped at a walk QUEUED for 41 seconds (41 [duck] WAITING
lines) and would fire the instant the pilot stopped -- while duckState stayed
1, so the cockpit symbol read "crouched" for the whole time a STANDING mech
walked around.  duckState is what the gauge strip draws; it has to tell the
truth.

Now: if the gate refuses, snap desired back to actual (duckState = duckActual)
and say so once, throttled.

This also confirms the authentic rule rather than assuming it.  Benched, a
crouch pressed while driving gives posture=0 and no squat -- exactly Lynx:
"When a mech STOPS, crouch button lowers its stance."  Immobilization while
crouched looks EMERGENT rather than gated: the leg channel parked in 'sqd'
produces no root motion to travel on, and the operator's read ("i think you
cant walk when you crouch") matches.  No [skate] in the driving case either.

Also guards re-issue: while 'sqd'/'squ' is playing (legAnimationState 2 or 3)
the transition owns the channel, so want != actual no longer re-fires
SetLegAnimation every frame.

Benched both cases:
  stopped  duckState -> 1 (crouch) -> SQUAT -> holds -> -> 0 (rise) -> RISE
  moving   REFUSED (not stopped): posture=0 ... duckState 1 -> 0
           0 squats, 0 queued waits
