0.36.6

(fix): Fix generated Rust wire tests for single-URL SDKs and pagination error tests. The wire test generator no longer emits config.environment = None; when the SDK was generated against a single base URL (since the environment field does not exist on ClientConfig in that case). The synchronous-paginator error-propagation tests now use ApiError::Configuration instead of the non-existent ApiError::Serialization variant, so the generated pagination.rs test module compiles.
