feat(R2-Q5): RemoteMotionSink DELETED — funnel dispatches straight into PerformMovement; AP-73 retired

The funnel's retail-ordered dispatches now go directly into the entity's
motion-table stack via Motion/MotionTableDispatchSink (Core):
ApplyMotion → PerformMovement(InterpretedCommand), StopMotion →
PerformMovement(StopInterpretedCommand). No axis collection, no
single-cycle priority pick, no Commit pass, no HasCycle probe, no
Run→Walk→Ready fallback chain — GetObjectSequence 0x00522860 +
is_allowed decide (closes H4, H5-callers, H11-callers, H15, H17-carry).
Run-while-turning now blends for real: the turn is a Branch-4 modifier
combined over the untouched run substate (AP-73 DELETED from the
register).

AnimationSequencer gains the public PerformMovement passthrough (lazy
initialize_state + locomotion velocity synthesis on success — AP-75;
remote body translation via PositionManager.ComputeOffset depends on
CurrentVelocity) and InitializeState(); HasCycle DELETED (the miss
hazard is structurally gone — GetObjectSequence checks the cycle before
any surgery; new conformance test pins sequence+state untouched on a
miss).

GameWindow: sink swap with the TurnApplied/TurnStopped ObservedOmega
callbacks (H17 carried verbatim — register AP-76, retire R6); spawn +
door sites run retail's enter-world order (initialize_state installs
the table default, the wire's initial motion dispatches unguarded — the
L.1c fallback chains deleted); despawn drains the pending queue via
HandleExitWorld (MotionDone success:false per entry, 0x0051bda0).

5 new MotionTableDispatchSink conformance tests (lazy init, Branch-4
turn blend + callback, Case-B stop unwind, Case-A stop re-drive,
miss no-op). Full suite green: 3,462 passed.

Live smoke vs ACE: in-world, NPC emote/Ready UMs dispatching through
the new path, [MOTIONDONE] completions firing across entities — first
live proof of the Q3→Q4→Q5 chain. Zero exceptions.

Registers: AP-73 deleted; AP-76 added.
