lekss361 ee87575052 fix(tradein/avito): anti-bot hardening — sleep + abort + shared session ... Production был заблокирован 23.05 17:48-17:55 MSK из-за tight loop без delay в detail enrichment (~20 req/sec к Avito). Все 3 подряд runs получили 403. Bundled fix: 1. AvitoBlockedError / AvitoRateLimitedError (новый avito_exceptions.py) 2. fetch_around, fetch_detail, fetch_house_catalog — raise на HTTP 403/429 3. scrape_pipeline: shared AsyncSession через весь sweep (один TLS handshake) 4. asyncio.sleep с +-20% random jitter между detail requests (default 7s) 5. Early abort: после 3 consecutive blocks — abort sweep + propagate 6. scrape_runs.mark_rate_limited (status=rate_limited vs failed/done) 7. detail_top_n default 20->10 в CitySweepStartRequest 8. logger.error вместо warning для 403/429 -> GlitchTip alert Confirmed root cause: prod logs показали 403 в 40-60ms intervals (blast pattern без delay между fetch_detail calls).		2026-05-23 23:00:23 +03:00
