Wall/ceiling/ground climb probes now skip any player collider (own and
remote) instead of only the local hierarchy, so running into another
chameleon no longer triggers the climb mechanic. New players are placed
on a per-clientId ring at spawn (host stays at origin) to avoid stacking
into one collision pile.
Also persists the serialized defaults of the recent network fields into
the Player prefab (incl. the spawnRingRadius inspector tuning) and a TMP
dynamic-atlas reset artifact.
