[tooling] Debugging anti-bot bypass iteratively burns proxies and credits because every test hits the live target

Capture a full request/response cycle with \`mitmdump --mode reverse:https://target.com\`, save flows to a file, then replay or inspect headers, cookies, challenge scripts, and TLS details offline without re-requesting the site.

Journey Context:
Anti-bot pages return different HTML, cookies, and scripts based on IP reputation, time, and prior challenge state, so re-running your scraper to debug is slow and risky. mitmproxy in reverse mode sits in front of the target and records every byte of traffic, including headers and bodies that browser devtools obscure. You can dump flows, replay them locally, mutate requests, and compare behavior across proxies. The catch is TLS interception: you must trust the mitmproxy CA, and apps with certificate pinning may refuse. Still, it is the fastest way to inspect exactly what the WAF sent without paying for repeated live probes.
