feat(pconline): add 太平洋电脑网 (PConline) adapter — search / list / info / param / price

[yixin-1024]

Adds a no-login (PUBLIC) adapter for 太平洋电脑网 (PConline, product.pconline.com.cn) — one of China's oldest digital-product catalogues (产品库: phones, laptops, cameras, CPUs, GPUs, tablets, watches…).

All pages are GBK-encoded + gzip'd SSR; Node's fetch inflates the gzip, then TextDecoder('gbk') decodes and the HTML is regex-parsed. No login, cookies or signature (same GBK family as the ZOL / autohome adapters).

Commands

Command	Source	Description
pconline list <category>	product.pconline.com.cn/<cat>/	产品大全 browse → name + 参考价 + detail URL (the discovery entry point)
pconline info <product>	<cat>/<brand>/<id>.html	overview: 名称 / 分类 / 品牌 / 重点参数
pconline param <product>	<cat>/<brand>/<id>_detail.html	full spec sheet (参数)

A product is addressed by its <category>/<brand>/<id> URL (printed by list) — the bare numeric id 404s on PConline, so info/param take the URL or the triple.

Deliberately not shipped (investigated; not login-gated, so login wouldn't help)

• keyword search — ks.pconline.com.cn 快搜 sits behind a JS/anti-bot challenge (HTTP 503 to a plain fetch). list covers discovery instead.
• merchant 报价 — the legacy shop_list_new2015.jsp API is retired (404) and the static price page carries only promo ads.
• 点评 — the mtp-list.jsp API returns empty shells.

The adapter never ships empty/unreliable data.

Quality gates (run locally)

• 12 vitest cases against frozen fixtures (list = 手机大全; info/param = iPhone17 Pro Max, mobile/apple/2718819)
• tsc --noEmit clean
• silent-column-drop new=0, typed-error-lint new=0 (zero baseline edits)
• doc-coverage 172/172
• Verified live across mobile / notebook / cpu categories

Note: fork-PR workflows stay at action_required until a maintainer clicks "Approve and run workflows", so the gates above were reproduced locally.

Added a 4th command: price.

Re-checked PConline against a logged-in browser session. Login itself unlocks nothing new, but driving the real browser surfaced the current price API that the first cut missed (it had probed the retired shop_list_new2015.jsp → 404). The live endpoint is a plain public JSON service:

ppc.pconline.com.cn/productPrice/list?pId=<id>&skuId=0&days=30&mallType=0

— separate host from the rate-limited 产品库, no login/cookies/signature, keyed by the numeric id alone (so price accepts a bare id too). Returns 历史最低价 (lowest tracked price + date) + each mall's latest tracked price (京东 / 苏宁).

search / 点评 stay out (verified still not login-gated): 快搜 is behind a slide-captcha anti-bot challenge (renders in a browser, 503 to a plain fetch), and the 点评 API returns empty shells.

16 vitest cases · tsc clean · silent-column-drop & typed-error-lint new=0 · doc-coverage green. Verified live (vivo S60 ￥3599 + 京东; iPhone17 Pro Max ￥9999).

Added a 5th command: search (browser).

Keyword search on 快搜 (ks.pconline.com.cn) is behind a slide-captcha anti-bot challenge — a plain fetch gets HTTP 503, but it renders fine in a real browser. So unlike the 4 PUBLIC commands, search is a browser command (Strategy.COOKIE, browser: true): it drives the browser bridge, lets the SSR result list render, then parses each .item-wrap card (.item-name[title] + .item-pic detail link + ￥price) out of the DOM. The parsed url feeds info/param; the id feeds price.

The anti-bot is not a login gate, but a logged-in Chrome reliably has the challenge already cleared. list still covers discovery via a plain fetch for anyone who doesn't want a browser.

PConline now has 5 commands: search (browser) + list / info / param / price (public). 19 vitest cases · tsc clean · silent-column-drop & typed-error-lint new=0 · doc-coverage green. Verified live: search "iPhone 15" → iPhone 15 / 15 Plus / Pro Max / Pro with real prices + 产品库 URLs.
