ExAgent.Message.Part.User (ExAgent v2.2.0)

A user prompt part: a string or a non-empty list of content parts.

Content parts are JSON-portable maps (atom or string keys):

%{"type" => "text", "text" => text}
%{"type" => "image_url", "url" => url} — http, https or data URL
%{"type" => "image", "data" => base64, "media_type" => "image/png"}
%{"type" => "file", "data" => base64, "media_type" => "application/pdf"}, with an optional "filename"

The model decides at request time whether it accepts each modality.
