* fix(bedrock): keep GPT tool-result images beside the tool result
Bedrock gpt-6.1-sol rejects an image nested in toolResult.content. Put it on the same user turn instead.
* fix(bedrock): read tool-result image support from the price map
OpenAI GPT rows on Bedrock Converse reject an image inside toolResult.content, so those images sit beside the tool result.
* fix: sync price-map test schema and import order
CI validates model_prices_and_context_window.json against an inline schema in test_utils, and ruff checks import order in converse_transformation.
* fix(bedrock): satisfy basedpyright in tool-result image helper
Drop Final assignments inside loops and use TypedDict key checks so the lint type-check gate stays within its merge-base ceiling.
* test(bedrock): cover tool-result image placement helper
Exercise Claude no-op paths, text-only GPT tool results, status preservation, and split text/image tool content for codecov.
* refactor(bedrock): reuse the shared tool-result image placeholder text
