Rumble Cloudflare bypass fetcher.

Node's TLS fingerprint (OpenSSL) is blocked by Rumble's Cloudflare config, while
curl_cffi's browser impersonation passes. This helper fetches a URL with
curl_cffi impersonating a Chrome client and prints the raw HTML to stdout.

Usage:  python3 rumble_fetch.py <url> [timeout_seconds]
Exit codes: 0 = ok (stdout = html), 2 = HTTP error / challenge, 3 = curl_cffi missing.
