- Added `NormalizeOpenAIFileData` utility to parse and validate file content, ensuring proper MIME type handling and base64 extraction. - Refactored translation logic to use normalized file data for Gemini, Antigravity, and Interactions processors. - Introduced comprehensive unit tests for both valid and invalid file data scenarios across all translators. Fixed: #4416
