Add 21 demo interaction + health check Playwright tests

Reactive island tests (14): counter, temperature, stopwatch, input-binding,
dynamic-class, reactive-list, stores, refs, portal, imperative,
error-boundary, event-bridge, transition, resource

Marshes tests (5): hypermedia-feeds, on-settle, server-signals,
signal-triggers, view-transform

Health checks (2): no JS errors on reactive or marshes pages

Known failures: island signal reactivity broken on first page load
(buttons render but on-click handlers don't attach). Regression from
commits 2d87417/3ae49b6/13ba5ee — needs investigation.
