Hi,

I got some code working for Anthropic Files API in ellmer and I have submitted a pull request to add support for this beta api. For quick summary, Claude offers 100GB of storage, no time limit as far as I can tell, maximum file size of 500MB, api calls that allow you to upload files, list uploaded files, delete them and download files generated by Claude.

A new Content object was added and a handler for the new object type in chat_anthropic.

Pull request: #760

I apologize for the subpar documentation. It is my first time generating documentation. Comments welcome.
