Persist each owner's paint snapshot on the MatchManager across the
despawn/respawn that happens on a lobby<->map scene switch, then reload
and rebroadcast it onto the freshly spawned avatar so painted meshes
survive the transition. Cleared on disconnect/shutdown to avoid stale
carry across sessions.
Isolate concurrent snapshot transfers by id so a respawning replica's
late-join request and the carry broadcast no longer share one reassembly
buffer (which decoded a mixed deflate blob -> "Corrupted data"), and drop
transfers with an older cutoff so a blank late-join cannot overwrite the
carried image.
