/**
 * Platform Queue Module
 *
 * Provides queue infrastructure for the Lilith Platform.
 * Wraps @lilith/queue-nestjs with platform-specific configuration.
 *
 * @example
 * ```typescript
 * // Root module (app.module.ts)
 * @Module({
 *   imports: [
 *     PlatformQueueModule.forRoot({
 *       redis: {
 *         host: process.env.REDIS_HOST || 'localhost',
 *         port: parseInt(process.env.REDIS_PORT || '6379'),
 *       },
 *     }),
 *   ],
 * })
 *
 * // Feature module
 * @Module({
 *   imports: [
 *     PlatformQueueModule.forFeature({
 *       name: 'email',
 *       owner: 'features/email',
 *       processor: EmailProcessor,
 *     }),
 *   ],
 * })
 * ```
