Sky Whales

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.
