CydandClaude Fable 5 eb8bba3195 BT410 Phase 5.3.6: look-button state machine -- full eyepoint composition
Reconstructs the binary's five-state LOOK machine (controls mapper tail,
part_013.c:396-459) as proper members/methods:

- MECHMPPR: LookState enum (None/Left/Right/Behind/Down) + lookState/
  previousLookState (out of reserved[24] -> [22]). InterpretControls picks the
  state from the look buttons each frame and on a CHANGE calls
  Mech::CommitLookState. BT_FORCE_LOOK=<1..4> dev hook.
- MECH: authored look angles lookLeft/Right/Front/BackAngle (deg->rad from the
  GameModel resource, guarded) + lookPitch/lookYaw + CommitLookState(int):
  side looks yaw by the authored angle, look-behind = yaw pi + lookBackAngle
  pitch, look-down = lookFrontAngle pitch, forward = identity. The per-frame
  eyepoint compose in Simulate adds the live Torso elevation on top.
  (reservedState [208] -> [202].)
- Deferred inside the commit (needs MechWeapon viewFireEnable/rearFiring):
  per-view weapon fire re-arm + HUD pip group-mask flip.

Verified headlessly: model reads clean authored angles (L=60 R=-60 F=-10 B=0
deg -- ModelResource layout confirmed again); BT_FORCE_LOOK=3 fires ONE commit
([look] state=3 yaw=3.14159 pitch=0) and the per-frame compose holds eyeYaw=pi
with eyePitch=0.349066 (lookBackAngle + the 20deg-clamped elevation). Zero Fail.
