feat: add 7 built-in middleware components inspired by Hono.js
New Middleware: - CORS: Cross-Origin Resource Sharing with full configuration support - Cookie Helper: Cookie management with signed cookie support (HMAC-SHA256) - JWT: JSON Web Token authentication (HS256/384/512) - Bearer Auth: Simple Bearer token authentication - Compression: Gzip and deflate response compression - Rate Limiting: Request rate limiting with customizable stores - Validator: Schema-based request validation Features: - Context store for middleware data sharing (get/set/get_client_ip) - Middleware export module with utility functions - Comprehensive property-based tests for all middleware - Example file demonstrating all middleware usage Files Added: - cors.v, cookie.v, jwt.v, bearer_auth.v, compress.v, rate_limit.v, validator.v - middleware.v (unified exports) - examples/middleware_demo.v - tests/test_*.v (9 new test files) Documentation: - Updated README.md with detailed middleware usage guide - Added Schema Builder API documentation
