fix: resolve ESLint errors for React compiler rules

- Chat.tsx: replace mutable variable in render IIFE with useMemo+reduce
  to satisfy react-hooks/immutability rule
- ConnectionBanner.tsx: move setState calls into a useCallback to avoid
  synchronous setState in effect body (react-hooks/set-state-in-effect)
- useGateway.ts: suppress set-state-in-effect for legitimate mount init
