Chat components subscribed to the entire chat store, so every
streaming delta re-rendered every assistant message. Subscribe to
narrow store slices and memoize ChatMessage so settled messages no
longer re-render on each delta. Cap getImageDataUri at 10MB, matching
the media picker, so oversized local images are not inlined into the
webview DOM.
