S1API 3.0.6

What's Changed

New API Surface

• Added custom mixing ingredient support, including MixIngredientDefinition, MixIngredientDefinitionBuilder, and MixIngredientItemCreator for runtime ingredient registration.
• Added custom product effect support through CustomEffect, CustomEffectBuilder, and EffectCreator.
• Added MixReactions for deterministic custom mixing reaction rules that can transform resulting product effects.
• Added NPC impostor selection APIs with NPCImpostorCatalog, AvatarImpostorDefinition, and avatar-default builder helpers for named, random, or mod-supplied impostor textures.

Fixes

• Fixed smoke-break cigarette setup for current game builds by resolving EquippableData / TPEquippedItem paths and preserving fallback behavior for older builds.
• Hardened the release and IL2CPP CI paths around build inputs, restore state, and artifact staging.

Documentation and Packaging

• Added docs for custom mixing ingredients and refreshed product, prefab, quickstart, installation, release-channel, FAQ, and module overview pages.
• Redesigned the generated documentation site templates and navigation.
• Updated release packaging so GitHub/Nexus use S1API-Forked-3.0.6.zip, while Thunderstore uses its dedicated Thunderstore archive.
• Bumped the package and Melon metadata version to 3.0.6.
