on-settle: increase wait from 2s to 4s — server fetch + settle hook
needs more time than the original timeout allowed.
server-signals: add actual cross-island signal test — click a price
button in writer island and verify reader island updates.
view-transform: fetch catalog before toggling view — the view toggle
only changes rendering of loaded items, not the empty state.
All 19 demo-interaction tests pass (was 14/19).
