feat(movement): spacebar charged jump with skill-based height

Browse source 
Hold spacebar to charge (0→1 over 1s), release to jump. Height from
GetJumpHeight formula using Jump skill via PlayerWeenie. Jump physics
use MotionInterpreter.jump() → LeaveGround() → get_leave_ground_velocity().

JumpExtent is returned in MovementResult (non-null when jump fires this
frame) so GameWindow can log and eventually send the server jump packet.
Double-jump is prevented by jump_is_allowed() checking Contact+OnWalkable
flags before allowing another jump. Tests updated to use charge-then-release
pattern matching the new input model.
