Global API Behavior

This project enforces consistent API behavior via:

• Global validation pipe (DTO validation)
• Global exception filter (standard error schema)
• Logging interceptor (structured request logs)
• Security Middleware: Helmet for secure HTTP headers, dynamic CORS configuration, and rate limiting to protect against excessive traffic.

These utilities are applied at application bootstrap.
