Matthew Farrellee a2a6a91cf5 fix(openai-compat): restrict developer/assistant/system/tool messages to text-only content ... **What:** - Added OpenAIChatCompletionTextOnlyMessageContent type for text-only content validation - Modified OpenAISystemMessageParam, OpenAIAssistantMessageParam, OpenAIDeveloperMessageParam, and OpenAIToolMessageParam to use text-only content type instead of mixed content - OpenAIUserMessageParam unchanged - still accepts both text and images - Updated OpenAPI spec files to reflect text-only content restrictions in schemas **Why:** - Enforces OpenAI API compatibility by restricting image content to user messages only - Prevents API misuse where images might be sent in message types that don't support them - Aligns with OpenAI's actual API behavior where only user messages can contain multimodal content - Improves type safety and validation at the API boundary **Test plan:** - Added comprehensive parametrized tests covering all 5 OpenAI message types - Tests verify text string acceptance for all message types - Tests verify text list acceptance for all message types - Tests verify image rejection for system/assistant/developer/tool messages (ValidationError expected) - Tests verify user messages still accept images (backward compatibility maintained)		2025-07-28 09:24:21 -04:00
