handle_fetch_resolution built InterceptResolution::Continue with url, method,
headers, and body hardcoded to None, so Fetch.continueRequest silently sent the
request unmodified. Playwright route.continue({ headers, url, postData }) and
Puppeteer request.continue reported success while their overrides were dropped.
op_fetch_url already applies all four (and re-validates a rewritten URL through
the SSRF gate); only the CDP layer was discarding them. Read url, method,
headers, and postData from the continueRequest params and pass them through.
Fixes#365.
