touhou_little_maid_vampirism

[New Features]

• Sunscreen Beacon support: Vampirism's Sunscreen Beacon block now grants sunscreen effect to vampire maids within range
• VampiresNeedUmbrellas optional integration: Vampire maids holding an umbrella in mainhand, offhand, or inventory automatically gain sunscreen protection; umbrella durability depletes under sunlight; creative umbrellas have infinite durability
• Biome sun-immunity: Vampire maids no longer take sun damage in vampire_forest and other IS_VAMPIRE_BIOME biomes, consistent with Vampirism player behavior

[Bug Fixes]

• Fixed Jade tooltip incorrectly displaying: previously any mob with the "Sanguinare Vampiris" effect would show the vampire maid tooltip, now only displays for EntityMaid
• Fixed mainhand item disappearing when vampire maid eats
