Fix player falling through terrain

Browse Source 
Player gets its own CapsuleShape3D (was a small CylinderShape3D, never
actually shared with anything — the shared oversized capsule flagged
earlier only affects the 4 mountain props, unrelated to the player).

Real cause of the fall-through: the crown collision is a zero-thickness
trimesh and the player spawned with exactly zero clearance sitting
right on the surface, a classic tunneling setup. Fixed by giving the
trimesh backface_collision (collide from both sides) and spawning the
player with a bit of headroom so it settles onto the floor instead of
starting embedded in it. Verified headless: player now falls from
spawn height to rest exactly on the surface and stays on_floor=true
over a 3s simulated run.
