Add bin/cloakserve — launches stealth Chromium with remote debugging
enabled so users can connect via connect_over_cdp() from the host.
Uses socat to forward 0.0.0.0:9222 to Chrome's localhost-only CDP port.
Usage: docker run -d -p 127.0.0.1:9222:9222 cloakhq/cloakbrowser cloakserve
Tested: all stealth checks pass via CDP, bot.sannysoft.com 54/54,
reCAPTCHA 0.9, zero detection regressions.
Add cloakhq/cloakbrowser Docker Hub image with Node.js, JS wrapper,
Xvfb headed mode, and cloaktest shortcut. Add launch feedback and IP
display to all examples. Update README Docker section for Docker Hub.
