Tab toggles between fly mode and player-controlled ground movement
when a live session is in-world. WASD walks/runs, A/D + mouse X
turns the character, Z/X strafes, Shift runs. PhysicsEngine resolves
positions against terrain each frame.
MoveToState sent on motion state changes (start/stop walking,
direction change, speed change). AutonomousPosition heartbeat sent
every ~200ms while moving. Walk/run/turn/idle animations resolved
locally via MotionResolver and played through the existing
TickAnimations path. ChaseCamera follows in third-person, mouse Y
adjusts camera pitch.
Tab on Escape also exits player mode gracefully. Mouse delta is
accumulated in the mouse-move callback and consumed+reset each
OnUpdate frame (no accumulation drift).
