The Composer slot only received onOpenFilePicker, which is an action rather than the ability to take files in, so no path that produces a File without the OS picker could be wired up from a slot. Add `onAddFiles` next to the existing flat props, so the change is additive and a type published in 1.18.0 keeps working. The built-in composer now attaches files pasted into it. The decision to claim the paste is made synchronously from the clipboard types, so text is never lost, and files are handed over unfiltered so a rejection surfaces its reason. Files arriving with an empty name (screenshots in some browsers) get one filled in from their MIME type; a name the browser did provide is left alone. `fileUploadEnabled` keeps meaning "file upload is configured" rather than folding in "no run in flight", which would make the attach button disappear for the length of every run instead of greying out. The composer slot already receives `loading`, so a composer that wants both facts can combine them. AILAB-370 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

You can now paste an image from the clipboard into the chat input and have it attached. The intended use is attaching a screenshot you just took.
The Composer slot now receives onAddFiles, which runs files through the chat's own file handling (validation, preview, transformers). DefaultComposer uses it to support paste, and the example's custom composer does the same.
When the clipboard also carries text, the text insertion is left alone and the file is attached alongside it.
