Client codegen chained .then().catch(), so a .catch() after .then()
caught exceptions thrown by the response body too. Switched to the
two-argument then(onFulfilled, onRejected) form, whose rejection
handler cannot see errors from the fulfilment handler.
SSR codegen wrapped both the transport call and the response-body eval
in the same try; only __wrnexusCallApi is now inside the try, and
__wrnexusEvalData runs after it, outside.
Also verifies (and locks in with a regression test) that GET query
numbers already coerce correctly through defineEndpoint + checkField,
and documents that in the typed-api-block spec.
Assertions in a .d.ts are inert under skipLibCheck: true, which the root
tsconfig sets. Proven during implementation by forcing skipLibCheck: false,
where the same assertion fires as TS2344. They move to a generated .ts file,
which skipLibCheck does not exempt.

A sectioned `api` block -- request / response / error -- callable on
demand from client code, typed against the API route contracts the types
generator already emits.
Records the constraints that shaped it: the current block cannot carry a
query string (isSafeApiPath rejects "?"), cannot interpolate (readPath
stops at "{"), has nowhere to put a body, and fetches once. And the one
that decides the type-safety mechanism -- generated build artifacts are
not type-checked, so enforcement goes into the generated .d.ts, which the
project's own tsc already compiles.

Markup in a .wrn file highlights but has no tag or attribute completion,
no tag closing, and no tag-level folding: the grammar's embeddedLanguages
mapping only affects tokenization, and VS Code's HTML language service
never runs on these documents.
The design extracts view blocks into a virtual HTML document where
everything outside them is blanked to whitespace of identical length, so
source positions and virtual positions are the same and no mapping table
is needed. Region detection is a tolerant scanner rather than the parser,
because completion fires while the document is mid-edit and unparseable.
Completion merges WRNexus and HTML entries into one list ranked by
sortText, which also fixes an existing bug: the extension and the server
both answer completion on '<' today, so VS Code concatenates two lists.
Two decisions worth review:
- HTML formatting is excluded. formatWrn already formats markup, knows
WRNexus syntax, and would fight a second formatter that is free to
rewrite spacing inside @click={...} and client:visible.
- Only auto-close-on-type is client-side. Linked editing is standard LSP
and lives in the shared server.

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
