Erik b1cf01029a fix(R4): #161 remote landing stuck in falling pose - apply-pass params decode
Retail's apply_interpreted_movement (0x00528600) does NOT dispatch with
ctor-default MovementParameters: the BN decomp smears the bitfield store
into the mush expression at raw 305778 - (word & 0x37ff) | cancelMoveTo<<15
| disableJump<<17 - which CLEARS SetHoldKey/ModifyInterpretedState/
CancelMoveTo. ACE MotionInterp.cs:444-449 confirms independently. Three
legs fixed, all retail decode, no adaptations added:

1. ApplyInterpretedMovement now builds the pass params retail actually
   uses (ModifyInterpretedState=false is load-bearing): no dispatch in the
   pass writes InterpretedState, so the airborne Falling substitution
   PRESERVES the wire's forward command and HitGround's re-apply
   dispatches it - the motion table plays the Falling->X landing link.
   The W6 entry-cache (built on the wrong "retail self-heals via hoisted
   registers" theory) is deleted; live reads are retail semantics. Raw
   arg3 decoded as DisableJumpDuringLink -> every (N,0) caller means
   allowJump=true; all 9 caller polarities fixed. copy_movement_from's
   current_style copy (raw 0051e757) added to the UM flat-copy.

2. Both GameWindow landing blocks cleared the Gravity state bit BEFORE
   Motion.HitGround(), whose verbatim state&0x400 gate then no-opped the
   whole retail re-apply; the UP-driven landing block never called
   HitGround at all. Both now run HitGround (minterp then moveto,
   MovementManager::HitGround 0x00524300 order) with Gravity still set,
   then do the DR bookkeeping clear (register row AP-81 added for the
   remaining flag dance, retire in R6).

3. K-fix17's forced SetCycle (both copies) deleted: it executed every
   landing but read the leg-1-clobbered ForwardCommand (0x40000015) and
   re-set the very Falling cycle it meant to clear.

Tests: new HitGround_AfterFall_RedispatchesPreservedForward_ExitsFalling
lifecycle pin; AirborneBody state assertion flipped (it had pinned the
bug value). Suite 3,964 green incl. the 183-case retail-observer trace.
Filed #164 (action-replay Autonomous bit, no current consumer).

Awaiting live verify: stand-still landing must exit the falling pose with
zero wire input.
