Reworked how sky whales spawn, and added a config.
**Spawning**
- Whales now spawn near players over the ocean (a Phantom-style near-player spawner) rather than the old biome-based natural spawn. They drift in around you and despawn by distance as you move on — no more empty oceans or a once-an-hour hunt.
**New config** — `config/skywhales-common.toml`, works the same in single-player and on a dedicated server:
- Rate & count: `spawnIntervalTicks`, `spawnChance`, `maxNearbyWhales` (+ radius).
- Where: `restrictToOceanBiome`, a `spawnOverVoid` toggle for void / lifted-island worlds, and the height/distance they appear around the player.
- Despawn: `immediateDespawnDistance`, a `forcePersistent` option, and a master switch.
**Internal**
- Replaced the custom mob category with vanilla CREATURE (drops an enum-extension). No client update required.
