route_intercept_captcha.py — Route-Intercept Captcha/Token Harvester (TOP-10 #1)
Teknik dari SYADAGENTIC captcha-solver (harvest-only pattern):
serve fake page di target origin → vendor JS asli jalan (byte-akurat) →
grab token/cookie → replay bundle {token, cookies, UA, proxy} utk pure-HTTP replay.

Cara kerja (universal):
1. Buka halaman palsu di ORIGIN target (route intercept) yang host widget captcha
2. Biarkan vendor real JS jalan (Turnstile/Cloudflare/reCAPTCHA dll)
3. Poll token field / cookie yang muncul
4. Return replay bundle utk request berikutnya (tanpa browser)

Dependensi: playwright (atau curl_cffi utk replay)
