/**
 * Campaign Repository
 *
 * Data access layer for Campaign entities.
 * Extends BaseRepository from @plyaz/db for consistent CRUD operations.
 *
 * Inherited from BaseRepository (used directly, no override needed):
 * - findById(id) - Get campaign by ID
 * - delete(id) - Hard delete campaign
 * - softDelete(id) - Soft delete campaign
 * - exists(id) - Check if campaign exists
 * - query() - Fluent QueryBuilder for complex queries
 * - count(filter) - Count campaigns matching filter
 * - findOne(filter) - Find first matching campaign
 *
 * Overridden with domain logic:
 * - findMany(options) - Default sorting by created_at DESC
 * - create(data) - Auto-generate ID and timestamps
 *
 * Domain-specific methods:
 * - findByStatus(status) - Get campaigns by status
 * - findByCreator(creatorId) - Get campaigns by creator
 * - findBySport(sport) - Get campaigns by sport
 * - countByStatus(status) - Count campaigns by status
