Add .task { store.connect() } so the app connects on open instead of requiring
a manual Connect tap (macOS already did this) — the defaults are production-ready
(public relay + account-derived room). This is also what surfaced the stale
"ttps://" typo bug: a corrupted saved server URL silently failed connect with no
visible error.
