Fix A: scale asyncio.wait_for timeout in run_yandex_city_sweep for
combos/center mode. Old 240s budget was sized for one geo anchor;
with 30 combos × 3 pages × ~21s each = ~1890s+ of work, sweep
timed out at 240s producing lots_fetched=0. Now computes:
sweep_timeout = max(240, num_combos * max_pages * (delay + 12) + 300)
For default 30×3×(9+12)+300 ≈ 2190s. Explicit-anchor mode keeps 240s.
Fix B: add scrape_pipeline.py to the `scraper` path filter in
deploy-tradein.yml so changes to sweep logic trigger scraper container
recreate. Previously only scrapers/** and scheduler.py were covered,
meaning #1658 deploy didn't recreate the scraper container.
Tests: 2 new unit tests for timeout computation (pure arithmetic, no
sleep) + explicit-anchor mode regression (wait_for called with 240s).
Full suite: 1844 passed, 2 deselected.
