Subject: [PATCH 1/4] fix(importer): reject used, like-new and refurbished
 listings at ingest (#1430)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

rate.products stores no condition, so a non-new listing linked to a
published master (exact model_key, variant or a master hint) fed its
lower price into the new device's min_price and the deal radar.

- ingestProduct throws NonNewListingError (code NON_NEW_LISTING) before
  anything is written when the normalizer detects a non-new condition,
  with or without a master hint (option A of #1430, no DDL).
- Trade-in offers for the buyer's old device ("nhận thu máy cũ",
  "thu cũ lên đời", "đổi máy cũ lấy máy mới") no longer read as used,
  so new listings are not dropped for them.
- The error is exported from @repo/crawlers (dist smoke).

Subject: [PATCH 2/4] fix(importer): only a non-new title rejects a listing;
 2nd Gen is new (#1430 review)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- The ingest check reads the title alone. Description boilerplate such as
  "không bán hàng cũ" or "99% khách hàng hài lòng" would drop new listings,
  so a description hit still only sets needs_review.
- "2nd" counts as used only in "2nd hand": "AirPods Pro 2nd Gen" and
  "iPhone SE 2nd generation" are new devices.
- The trade-in strip also covers "thu máy cũ đổi máy mới" and
  "thu mua máy cũ".

Subject: [PATCH 3/4] fix(importer): check the sanitized title; a bare 98% is
 not a condition (#1430 Codex)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- The normalizer sets title_condition from the sanitized title, and the
  ingest check reads it, so a control character inside "Máy cũ" no longer
  slips a used listing past the check.
- A bare "98%" or "99%" (such as "Chống ồn 98%") no longer reads as
  like-new; a percentage counts only after máy, ngoại hình, hình thức,
  keng or pin, besides the existing mới, đẹp and zin.
