/**
 * CrossReferenceIndexGenerator - Indexes cross-file references into ContentIndex
 *
 * ARCHITECTURE:
 * This generator populates the ContentIndex trie with annotated entries for all
 * content types that can be referenced across files. This data powers autocomplete
 * suggestions in both Monaco (web editor) and VS Code.
 *
 * REFERENCE TYPES INDEXED:
 * - Geometry identifiers (from .geo.json files)
 * - Animation identifiers (from animation files)
 * - Animation controller identifiers
 * - Render controller identifiers
 * - Particle identifiers
 * - Fog identifiers
 * - Sound event names (from sound_definitions.json)
 * - Loot table paths
 * - Recipe identifiers
 * - Biome identifiers
 * - Spawn rule identifiers
 * - Dialogue paths
 * - Function paths (.mcfunction files)
 * - Structure paths
 *
 * TYPES ALREADY INDEXED ELSEWHERE (not duplicated here):
 * - Entity IDs → TypesInfoGenerator (AnnotationCategory.entityTypeSource)
 * - Block IDs → TypesInfoGenerator (AnnotationCategory.blockTypeSource)
 * - Item IDs → TypesInfoGenerator (AnnotationCategory.itemTypeSource)
 * - Feature IDs → TypesInfoGenerator (AnnotationCategory.featureSource)
 * - Texture file paths → TextureInfoGenerator (AnnotationCategory.textureFile)
 *
 * RELATED FILES:
 * - ContentIndex.ts — The trie data structure and AnnotationCategory enum
 * - TypesInfoGenerator.ts — Indexes entity, block, item, feature IDs
 * - TextureInfoGenerator.ts — Indexes texture file paths
 * - langcore/json/CrossReferenceCompletionSource.ts — Queries this data for completions
