scrape_schedules had no interval column -> every source ran daily. Add
interval_days from default_params (default 1, backward-compatible) so
compute_next_run_at can schedule N days ahead. Set avito_full_load_exhaustive
to interval_days=7 (weekly full pass for last_seen/delisting + silent price
edits); avito_full_load stays daily incremental.
run_avito_full_load gains incremental_days param -> passes since= to the
(merged) incremental SERP engine. avito_full_load schedule flipped to
incremental_days=2 (shallow, date early-stop -> avoids deep-pagination 429
bans). New avito_full_load_exhaustive source runs the full walk weekly to
refresh last_seen (10-day delisting TTL) and catch silent price edits.
Подключает prod-проверенный run_cian_full_load (exhaustive региональный сбор
Cian ЕКБ вторички, room×price партиционирование, incremental on_bucket save) в
in-app scheduler как recurring-источник cian_full_load (окно 20-22 UTC — отделено
от cian_city_sweep/history_backfill на 2-5 чтобы не конкурировать на shared
kf-прокси).
run_cian_city_sweep теперь NB-only (newbuilding_only=True default): SERP-фаза
сохраняет только novostroyki-лоты, вторичку отбрасывает — ею авторитетно владеет
full_load. Убирает дубль secondary SERP-сейва. DETAIL/HOUSES-фазы не затронуты.
