Erik 0f099bb652 feat(D6.2a): port CMotionInterp motion normalization + unify local velocity/turn/jump 
Ports retail's raw->interpreted motion normalization and routes the local
player's velocity through it, so backward/strafe come from the retail source
instead of hand-mirrored controller code (retires register TS-22 + UN-5).

MotionInterpreter (decomp-verbatim, Ghidra/ACE-cross-checked):
- adjust_motion (0x00528010): WalkBackward->WalkForward (x-0.649999976),
  TurnLeft->TurnRight (x-1), SideStepLeft->SideStepRight (x-1), sidestep scale
  0.5*(WalkAnimSpeed/SidestepAnimSpeed), RunForward early-return, per-channel
  holdkey fallback to CurrentHoldKey.
- apply_run_to_command (0x00527be0): WalkForward->RunForward when speed>0 +
  UNCONDITIONAL *runRate; TurnRight *1.5; SideStepRight *runRate clamp +/-3.0.
- apply_raw_movement (0x005287e0): copy raw->interpreted, adjust the 3 channels
  with per-channel hold keys.
- WalkAnimSpeed unified to the retail-exact 3.11999989f (was 3.12f).

PlayerMovementController: build ONE RawMotionState from MovementInput at
forward_speed=1.0 (apply_run_to_command applies the run rate — a pre-scaled
speed would double-scale), run apply_raw_movement, then take grounded + jump
velocity straight from get_state_velocity (now correct for all directions) and
drive the keyboard turn omega from the interpreted turn_speed (BaseTurnRate x
turn_speed = the same pi/2 formula the remote path uses; numerically identical
to the old TurnRateFor). Deleted the hand-mirrored backward(x-0.65) /
strafe(x+-1.25) formulas in both the grounded and jump blocks. Mouse turn and
the auto-walk path are untouched.

Retail-faithful behavior changes (confirm in smoke): strafe is now
1.25 * ~1.248 * runRate = ~1.56*runRate, clamped via SideStepSpeed<=3.0 so
|v.X|<=3.75 (was 1.25*runRate, no scale/clamp); backward is unchanged
(3.12*0.65*runRate); backward/strafe-left velocity now comes from the pipeline
instead of returning zero. Forward run pace unchanged (4.0*runRate).

Tests: MotionNormalizationTests (17, adjust_motion/apply_run_to_command) +
MotionVelocityPipelineTests (10, apply_raw_movement->get_state_velocity golden
velocities incl. the strafe clamp + turn speeds). Full suite green (3255).

Register: TS-22 + UN-5 deleted (retired); TS-34 added (adjust_motion creature
guard is a no-op — IWeenieObject has no IsCreature; correct for the only caller,
the player). Pseudocode: docs/research/2026-07-01-d6-motion-interp-pseudocode.md.

NEXT D6.2b: the echo-gated wire forward_speed=1.0 question (evidence suggests
ACE relays rather than recomputes; verified via the smoke echo).
