fix(bedrock): skip redundant output_config normalization on Converse reasoning_effort path

cursoragent · yassin-berriai · cursoragent · commit 55607667f836 · 2026-05-26T22:13:05.000Z
When reasoning_effort is mapped via _handle_reasoning_effort_parameter, the
resulting output_config is already normalized via
normalize_bedrock_opus_output_config_effort. Mark it as normalized so
_prepare_request_params can skip the redundant call (and the associated
get_model_info lookup) on every request.
