feat(monkey): add cheeky banana-throwing monkey addon

New silverlabs:cheeky_monkey mob that wanders the lobby watching players
and throwing harmless (knockback-only) silverlabs:banana_projectile at
them. Drops 1-2 silverlabs:banana (food) on death. Spawn rules target
jungle biomes for future deployment to survival worlds; for now the pack
is bind-mounted into the lobby service only.

Also bundles a stray docker-compose tidy from earlier local work
(Jamie's world seed pinned, pet addons dropped from Jamie).
