Conversation
- Add Extension to imports in openapi/schematic.rs - Implement ParameterProvider trait for Extension<T> with empty parameter generation - Re-export Extension from lib.rs and prelude for user convenience - Add test to verify Extension parameters work with the api macro - Extension parameters are now properly excluded from OpenAPI specs, similar to State and Request This allows handlers to use Extension<T> for middleware-injected values without polluting the OpenAPI documentation with parameters that don't come from the HTTP request.
