Patch Changes

• #11421 041a755 Thanks @priprocess! - Preserve the generic tool_search_tool_result block type in streaming output and message payload conversion. The Anthropic API emits this un-suffixed type for both tool search variants; previously only the variant-suffixed names were allowlisted, so multi-turn conversations using tool search still failed with INVALID_TOOL_RESULTS after a client-tool round-trip.
