🔐 JWT Role Middleware - Refactored Architecture

✨ What's New

• Improved Architecture: Middleware now uses a configuration object pattern for better separation of concerns
• Enhanced Security: Secret key and environment mode (devops/production) are configured once at middleware creation
• Better Performance: Configuration is pre-computed, reducing runtime overhead
• Cleaner API: Simplified usage with NewJwtRoleMiddleware() and config.Handler()

�� Key Improvements

• Eliminated Parameter Duplication: No more passing secret and devops flags in every handler call
• Reduced Error Risk: Configuration validation happens at creation time, not runtime
• Improved Maintainability: Single configuration object can be reused across multiple routes
• Better Testing: Cleaner test structure with consolidated test suite

�� Usage

// Create middleware configuration once
authConfig := middleware.NewJwtRoleMiddleware(false, "your-secret")

// Reuse for different routes
app.Use(authConfig.Handler(false, "admin", "user"))
app.Use(authConfig.Handler(true, "admin"))  // pass mode

�� Testing

• 28 comprehensive tests covering all scenarios
• Single benchmark with consistent ~29μs performance
• 95%+ test coverage with edge cases and error handling

�� Breaking Changes

• Removed deprecated JwtRoleMiddleware() function
• All code must now use the new configuration-based API
