CydandClaude Fable 5 87b1c048cf BT410 Phase 5.3.5: eyepointRotation -- torso elevation pitches the eye/aim-ray, not a joint ...

Investigated the next planned binding (elevation -> gun joints jointlgun/
jointrgun) before implementing it, and found it was the wrong target: BT411's
own reverse-engineering history records that NO gun/arm elevation joint exists
in the authentic engine. The pod's stick-Y aim pitches the COCKPIT EYE and the
weapon boresight directly (mech4.cpp @~5219, pixel-calibrated against real
screenshots) -- the torso geometry never tilts for elevation on this mech
family. Reconstructing a gun-joint binding would have been invented behavior.

- MECH.HPP: EulerAngles eyepointRotation member (out of reservedState, now
  [208]) + GetEyepointRotation() accessor.
- MECH.CPP: composed each frame in Simulate -- eyepointRotation =
  EulerAngles(Radian(Normalize(lookPitch+elevation)), Radian(Normalize(lookYaw)),
  Radian(0)), reading Torso::CurrentElevation() via sinkSourceSubsystem.
  lookPitch/lookYaw are 0 until the look-button wave (BTCommitLookState) lands.

Verified: BT_FORCE_ELEV=0.8 -> torsoElev and eyePitch both read 0.349066 (the
authentic 20 degree resource limit) every frame, exact match; neutral -> 0.
Zero Fail. Corrected TORSO.NOTES.md's prior (wrong) "next: gun joints" note.
