Implemented and removed. A render-phase flag cleared on a microtask is
still set when React runs effects, so islands writing from an effect —
the documented correct pattern — would throw. The flag also cannot be
set for an island's own re-renders, so real violations pass silently.
Detecting React's render phase reliably needs React internals, which is
not acceptable in a shipped framework. React already reports the real
hazard, and the getSnapshot caching requirement covers the loop case.

Adds the approved design for consuming npm React components as
client-only islands inside WRNexus, without changing the SSR-first
rendering model.
Key decisions:
- New isolated @wrnexus/react package; react/react-dom as optional peers
- Client-only by default, SSR deferred to v2
- Islands declared via .tsx imports in .wrn frontmatter
- Store access via useSyncExternalStore, with the snapshot cache in the
adapter so @wrnexus/store stays untouched
- Bundling extends the existing Bun pipeline; React as a shared chunk
- Routes with no islands must still ship zero framework JavaScript
