feat: Python traffic generator with realistic varied HTTP/HTTPS traffic
- Replace curlimages/curl with Python stdlib traffic generator - 200 requests, 10 workers, 16 scenario types: browsers (Chrome/Firefox/Safari/Edge/mobile), bots (Googlebot/Bing/curl/wget), GET/POST/HEAD/PUT/PATCH/DELETE/OPTIONS, HTTP + HTTPS - Multiple SSL contexts (default, TLS1.2-only, TLS1.3-only, few_ciphers) → 4 distinct JA4/JA3 fingerprints per test run - Realistic headers: Accept, Accept-Language, Sec-Fetch-*, Referer, X-Forwarded-For, Cookie, Cache-Control - JSON payloads, form data, CORS preflights - DB always reset (down -v) at start of each test run - Enhanced Phase 5 checks: distinct UAs, method variety, JA4/JA3 counts + uniqueness Results: 199/200 OK, 24 distinct UAs, 7 HTTP methods, TLS 1.2+1.3, 4 JA4 fingerprints Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
