Replaced the chat shell on mobile with a real port of the web Chat: polled thread on a 2.5s loop, SSE activity stream for live "what the agent is doing" status, optimistic sends, steering on send-while-typing, and the ADR 0028 approval cards with the accent spine. Wrote a MessageBody that handles image URLs, links, and bold the way the web does, since RN won't let images sit inline in Text. Also swept out the Expo starter detritus that had been sitting in components and hooks (themed-text, themed-view, animated-icon, the web app-tabs, the global.css), and added ESLint config plus expo-network while I was in there. The deletes feel as good as the additions.
