Auth-limbo + login-restore fix for Paper 1.21+. Bypasses the
AuthMe `teleportOnLogin` race (PaperMC/Paper#4085) by listening at
MONITOR priority, reading the player's saved quit-location from
AuthMe's SQLite DB, pinning the destination chunk via
addPluginChunkTicket, then chaining getChunkAtAsyncUrgently and
teleportAsync.
Bundles a void auth_limbo world via custom ChunkGenerator so the
plugin removes the need for Multiverse-Core for offline-mode auth flows.
