Winter 0.123.0

Images in code sessions

Paste or drag an image into a code session's message box, or press ctrl+v in the terminal app, and it
appears as [Image #1]. Pasting an image file's path works too.
Large images, such as Retina screenshots, are shrunk when you attach them, so they always fit.
Your message shows [Image #n]. The model receives the saved image and looks at it.
If the selected model can't read images, Winter says so as soon as you attach one: "The selected
model doesn't support images".
Chat and dispatch sessions are unchanged for now.

When the model names a file in its reply, the path is a link. Click it and the file opens in the
right-hand panel.
An image path also shows a small preview. Click it to see the full image in the panel, fitted to
size; double-click for actual size.

When a model reads an image file, it now sees the picture itself on every provider. Before, it got
the image's raw data as text.
Images returned by MCP tools and notebook plots reach the model as images too.
Long sessions with many screenshots stay within each provider's image limits instead of failing.
A model that can't read images gets a short note instead of unreadable data.

This release runs on Winter agent SDK 0.0.36 and runtime SDK 0.0.15.
