…ision pipeline When users send images as documents (Telegram file picker), they were rejected with "Unsupported document type" because SUPPORTED_DOCUMENT_TYPES only includes text/office formats. Add SUPPORTED_IMAGE_DOCUMENT_TYPES to base.py and handle them in telegram.py before the document check. - Add SUPPORTED_IMAGE_DOCUMENT_TYPES constant to base.py - Add MIME reverse-lookup for image types in telegram.py - Route image documents through cache_image_from_bytes + vision pipeline - Handle media groups for image documents Closes: NousResearch#20128, NousResearch#18620
