CydandClaude Fable 5 3364b65ae8 BT410 Phase 5.3.1: Mech::Simulate motion core -- mech integrates motion per-frame
Installs Mech::Simulate as the mech's per-frame Performance (was DoNothingOnce).
Reconstructs the load-bearing spine of the 1995 Simulate (mech4.cpp @004ab430):
integrate the body velocity into localOrigin (linearPosition.AddScaled(..,
worldLinearVelocity, dt)) and commit the Origin to the world transform with the
engine idiom (localToWorld = localOrigin, per ENTITY.cpp:988 / MOVER.cpp:850).

Uses the NAMED engine base Mover fields (localOrigin/localToWorld/
worldLinearVelocity) -- BT411's MechBaseLayoutCheck proved the WinTesla decomp's
raw this+0x100/0x260 offsets actually stomp those base fields; the clean 1995
build addresses them by name.

- MECH.HPP: Mech Performance typedef + SetPerformance + Simulate() decl.
- MECH.CPP: SetPerformance(&Mech::Simulate) at ctor tail; Simulate body.

Verified headlessly (BT_MECH_LOG "[sim] mech pos=" 1Hz): BT_DRIVE="5,0,10"
advances the mech +5.0/s x, +10.0/s z (y fixed) = exactly the injected world
velocity; no BT_DRIVE -> worldLinearVelocity is 0, mech holds spawn pose. Zero
Fail/Exception either way. BT_DRIVE is a retained dev hook for headless motion.

Deferred (locomotion wave): gait-cycle self-propulsion feeding worldLinearVelocity
(IntegrateMotion->AdvanceBodyAnimation, steered by mapper throttle/turn), heading
integration, terrain-height drop, cockpit telemetry filters.
