📄 Description

With support for multimodal models becoming more varied and common it is important for clients to be able to easily see what capabilities a model has. Retuning these from the show endpoint will allow clients to easily see what a model can do.

This change adds a capabilities field to the show response so that clients can easily see what features a given model supports. It also adds a vision capability based off the presence of a vision.block_count KV.

Sample API response:

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
