Serve a binding's preview snapshot (committed definition)

GET

/api/workspaces/{workspaceId}/apps/{id}/bindings/{name}/snapshot

const url = 'http://localhost:8080/api/workspaces/example/apps/example/bindings/example/snapshot';
const options = {method: 'GET', headers: {cookie: 'auth_session=<auth_session>'}};

try {
  const response = await fetch(url, options);
  const data = await response.json();
  console.log(data);
} catch (error) {
  console.error(error);
}

curl --request GET \
  --url http://localhost:8080/api/workspaces/example/apps/example/bindings/example/snapshot \
  --cookie auth_session=<auth_session>

The first N rows of the committed binding’s stored parquet, in build order (schema + total row count), for useQuery(name, { snapshot: true }) to paint before DuckDB-WASM loads. 404 when the binding was never built, was built before snapshots existed, or has a column type a snapshot cannot carry — callers wait for the parquet.
