feat(biome): abyssal bioluminescent + glow blocks + abyssal jellyfish + particles
- BlockDatabase: GLOW_CORAL_CYAN(10), GLOW_CORAL_VIOLET(11), LAVA_VENT(12) with emission data - WorldGenerator: abyssal blocks at y<-40 (cyan 4%, violet 1%, vent 0.5% via 3D noise) - Chunk.gd: multi-surface mesh (solid + 3 emissive surfaces with StandardMaterial3D emission) - MobSpawner: abyssal jellyfish spawn when player y<-30, max 8 - AbyssalJellyfish: cyan fluo, slower, double damage (10), bioluminescent flash on attack - BioluminescentParticles: 200 cyan-green particles follow player, only emit in abyss Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
