Report #517

[tooling] Blocked by TLS/JA3 and HTTP/2 fingerprinting despite using correct headers

Use curl-impersonate wrapper scripts \(e.g., curl\_chrome116\) or libcurl-impersonate with the CURL\_IMPERSONATE env var to clone a real browser's TLS \+ HTTP/2 handshake instead of just rotating User-Agent.

Journey Context:
Most HTTP clients use OpenSSL signatures that differ from browsers. Anti-bots fingerprint the TLS ClientHello \(JA3/JA4\) and HTTP/2 SETTINGS frame. curl-impersonate compiles curl against BoringSSL/NSS with patched extensions, ALPN, and HTTP/2 pseudo-header order to match Chrome/Firefox/Safari/Edge exactly. It is faster and cheaper than a headless browser but only works for non-JS/WAF fingerprinting layers, not JS challenges or Turnstile.
