- Remove reCAPTCHA/hCaptcha body detection on HTTP 200 (false positives
  on pages with login forms like old.reddit.com)
- Rotation fallback switches Chrome to Safari instead of cycling Chrome
  versions (fundamentally different TLS/H2 fingerprint)
- max_rotations default 10 -> 1 (one rotation attempt, then give up)
- Rotation delay = rate limiter interval + 1s (replaces aggressive 0.5s
  exponential backoff that hammered sites)
