player_movement_controller.gd: use Node + get_node() instead of
typed MovementStateMachine + $ shorthand so runtime set_script paths
don't crash on @implicit_ready
- state_wall_run.gd: typed ray_origin/ray_end as Vector3
- test_level_builder.gd: restructure builder to put MovementStateMachine
+ state children under Player, attach camera under Player too
- player_movement_controller.gd: @onready uses get_node so type is not inferred
- state_dash.gd: Basis*Vector4 → Basis*Vector3 (no Vec4 in Godot 4.2)
- state_ground.gd: shape_owner_get_shape(0) → (0, 0); typed Variant vars; typed ray/normal
- state_slide.gd: same shape API fix + unique shape vars per branch
- state_wall_run.gd: split 'and' line into single typed bool expression
