What is in this change?
Adds support for base64-encoded document attachments in API chat endpoints. Non-image attachments are now parsed and included in the chat context, allowing the LLM to read and respond based on document content. Image attachments continue to work as before.
Additional Information
Documents are processed via the Collector API and their content is added to the context before generating responses. Temporary files are cleaned up after processing.
