The appbar's <Avatar> reads avatarUrl from the localStorage profile
mirror. Without a global fetcher, that mirror only got populated when
the user navigated to /profile, so a fresh browser session showed
initials in the appbar until then.
- ProfileBootstrap component runs in root.tsx alongside
LlmConfigBootstrap. On mount and on session change, fetches the
arcadia profile and caches the resolved avatar URL.
- profile.tsx loadAccount now also persists the URL into localStorage
on initial fetch (was in-memory only) so it survives reloads.
