"""Unit tests for per-anchor watchdog timeout in city sweeps (#880).

Verifies that ANCHOR_TIMEOUT_SEC is applied to all three sweeps (avito / cian / yandex):
  (a) A hung anchor (asyncio.sleep(large)) doesn't freeze the whole sweep.
  (b) TimeoutError branch: errors_count incremented, anchor logged as timed-out.
  (c) Sweep proceeds to the next anchor after the timeout.
  (d) mark_done is called when the sweep finishes all anchors.

All tests are network-free — they monkeypatch the inner scrape call.
