[Feature Request] Upload file support

[Lozgemk]

Hi, thanks for the great project. I wonder if there are near plans to support file upload. Since now many models are multi-modal and support native file processing (without local preprocess or embedding), I assume it would not be very difficult to use the native API.

I believe this feature is very important. However, one of the main challenges is that file upload interfaces vary largely between various API providers, differing to OpenAI's implementation, which makes compatibility more difficult to achieve. Especially since Daan aims to remain lightweight and continue offering a web-based version as static service.

We will first prioritize supporting the OpenAI interface in the future, and this feature will mainly be available on the desktop version.
