Mech phase 2: reconstruct Gyroscope (: PowerWatcher) -- Mech gyroSubsystem
Eye/body stabilisation subsystem. Full resource struct + tuning members (springs/damping/noise/percentages/damage multipliers) reconstructed; the eye/body dynamics accumulators held in a reserved pad until the per-frame GyroscopeSimulation is reconstructed (phase 5). Ctor chains PowerWatcher + copies tuning; statics/dtor/test/reset real; sim staged. BT: 28 ok. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
