1. Implementation

• 1.1 Change AccumulateLatest(Time.fixedDeltaTime) to AccumulateLatest(kServerSimulationStepSeconds) in MovementComponent.FixedUpdate()

2. Verification

• 2.1 Run all EditMode tests ensure no regression
• 2.2 Local loopback validation — controlled-player loopback movement no longer shows jitter under steady turn-and-move input
