Fetch Headers serialization: SDK passes `Headers` instances to fetch, `JSON.stringify(Headers)` produces `{}` — normalize to plain Record via `.entries()` + 3. Response body async iterator: added `Symbol.asyncIterator` with explicit `Promise.resolve()` (not async generator) for SDK's ReadableStreamToAsyncIterable + 4.
