/**
 * Collection Schema API Route Handlers for Next.js
 *
 * These route handlers can be re-exported in your Next.js application to provide
 * collection schema management endpoints at /api/collections/schema.
 *
 * Services are auto-initialized on first request using environment variables:
 * - DB_DIALECT: Database dialect ("postgresql" | "mysql" | "sqlite")
 * - DATABASE_URL: Database connection string
 *
 * @example
 * ```typescript
 * // In your Next.js app: app/api/collections/schema/route.ts
 * export { GET, POST } from 'nextly/api/collections-schema';
 * ```
 *
 * @module api/collections-schema
