fix: wrap AI block in try/catch for graceful fallback when Shakespeare API fails

If the AI call throws (400, 401, network error, etc.), Sasquatch now:
- Catches the error silently (logs to console as warning)
- Falls back to the static FAQ answer if one matches
- Falls back to a friendly "try again" message if no FAQ match
- Never shows a crash or blank response to the user

The toolMatch reference inside the try block is properly scoped so the
isLive flag works correctly when the full AI + CVM flow succeeds.
