• [orchestration] Support file input for user messages.
  File inputs have a type of file and include a file_data field with a URL such as a HTTP URL or a data URL.
  Local files must be provided as data:MEDIATYPE;base64,DATA with a non-empty media type and valid base64 content.
  Availability of different file types depends on the capabilities of the underlying model and tools.
  GPT-models do not support file inputs with the orchestration API at this time. (b822da9)
• [rpt] Align parquet endpoint types with the RPT API types. (08c6137)
