/**
 * Files Repository
 *
 * Data access layer for Files/Media entities.
 * Extends BaseRepository from @plyaz/db for consistent CRUD operations.
 *
 * Inherited from BaseRepository (used directly, no override needed):
 * - findById(id) - Get file by ID
 * - delete(id) - Hard delete file
 * - softDelete(id) - Soft delete file
 * - exists(id) - Check if file exists
 * - query() - Fluent QueryBuilder for complex queries
 * - count(filter) - Count files matching filter
 * - findOne(filter) - Find first matching file
 *
 * Overridden with domain logic:
 * - findMany(options) - Default sorting by created_at DESC
 * - create(data) - Auto-generate ID and timestamps
 *
 * Domain-specific methods:
 * - findByUserId(userId) - Get all files for a user
 * - findByEntityId(entityType, entityId) - Get files for an entity
 * - findByStoragePath(path) - Find file by storage path (for deduplication)
 * - countByUserId(userId) - Count files for a user
