/**
 * ContentModule - Configurable module for Content management.
 *
 * Supports optional extension via ContentExtensionConfig. The configuration
 * shapes both the entity descriptor and the generated Cypher:
 * - `additionalRelationships` — extra relationships on the descriptor, an
 *   OPTIONAL MATCH per relationship, and the related node in the RETURN
 * - `ownerMatchPattern` — the owner edge's relationship types / direction
 * - `requireTldr` — restricts reads to records carrying a non-empty tldr
 * - `metaFields` — extra computed meta keys hydrated by extra OPTIONAL MATCHes
 * - `serialiseAuthor` — whether the `author` relationship exists at all
 *
 * With no configuration the module behaves exactly as it always has.
 *
 * The module is `global: true` so `ContentCypherService` can be handed to
 * RelevancyService from any module. It is nonetheless excludable from the
 * foundations composition by class reference
 * (`FoundationsModule.forRoot({ exclude: [ContentModule] })`).
 *
 * @example
 * ```typescript
 * // Without extension (default behavior)
 * ContentModule.forRoot()
 *
 * // With extension
 * ContentModule.forRoot({
 *   additionalRelationships: [
 *     { model: topicMeta, relationship: 'HAS_KNOWLEDGE', direction: 'in', cardinality: 'many' },
 *   ],
 * })
 * ```
