App chat: search, unread badges and shortcuts

Find past conversations with full-text search, see which threads have new messages, refine generated images, and navigate with keyboard shortcuts.

Unread badges. Thread rows now show an unread indicator when there are new messages you haven't read yet, so you always know which conversations need attention.
Image refinement. Generated images include a refine action in the lightbox, click it to start an edit prompt that uses the original as a reference.
Keyboard shortcuts. Navigate between threads, open compose, and trigger common actions with keyboard shortcuts. Customize bindings in the new Keyboard Shortcuts page under Settings.
