Next.js API Route Builder with Validation and Error Handling

Create a Next.js App Router API route at app/api/[endpoint]/route.ts. Requirements:
- Export async GET/POST/PUT/DELETE handler functions
- Use Zod schemas for request body and query parameter validation
- Implement proper error handling with try/catch and typed error responses
- Return consistent JSON response shape: { data, error, message }
- Add proper HTTP status codes (200, 201, 400, 401, 403, 404, 500)
- Include request body type inference from Zod schema
- Add rate limiting check if this is a public endpoint
- Use NextRequest and NextResponse from next/server
- Log errors to console with context (route, method, timestamp)
- Handle edge cases: empty body, malformed JSON, missing fields
- Follow existing API patterns in this project's codebase
