Pull request overview

Updates the FastEdge test runner and fixtures to preserve multi-valued HTTP headers end-to-end—most importantly Set-Cookie per RFC 6265 §3—across runners, wire protocols (WebSocket/API), frontend rendering, schemas, and test assertions.

Changes:

• Introduces a lossless header projection (string | string[]) for hook/full-flow results and HTTP-WASM responses (Node IncomingHttpHeaders-shaped), with supporting helpers (firstValue, flattenToMap).
• Fixes fetch-ingestion paths to keep multiple Set-Cookie values as string[] and updates fixtures (Rust/JS/AS) to emit multiple cookies for regression coverage.
• Updates tests, JSON schemas, and generated docs to reflect multi-value header semantics and improved type exports.

test-applications/http-apps/js/src/http-responder.ts	Emits multiple Set-Cookie values via Headers.append() when x-set-cookies is present.

frontend/src/hooks/websocket-types.ts:101

• HttpWasmRequestCompletedEvent.data.response.contentType is typed as string here, but the backend event type (server/websocket/types.ts) and IWasmRunner.HttpResponse allow string | null. To keep the frontend WebSocket types truly mirroring the backend (and avoid runtime surprises if a null content-type is ever emitted), widen this to string | null (or normalize to "" on the server before broadcasting and document that invariant).

    response: {
      status: number;
      statusText: string;
      headers: Record<string, string | string[] | undefined>;
      body: string;
      contentType: string;
      isBase64?: boolean;
    };
