feat(zol): 中关村在线 (ZOL) no-login adapter — search / rank / param / price / koubei / pic

[yixin-1024]

What

Adds a 中关村在线 (ZOL, zol.com.cn) adapter — China's largest digital-product
catalogue (phones, laptops, cameras, …). Three read-only commands:

Command	Source	Returns
zol search <keyword>	search.zol.com.cn/s/all.php	name + 报价 + product id
zol param <product>	detail.zol.com.cn/0/<id>/param.shtml	full spec sheet (dimensions/screen/battery/chipset…)
zol price <product>	detail.zol.com.cn/0/<id>/price.shtml	per-platform/seller offers + buy links

How

All three are Strategy.PUBLIC (browser: false) — a plain fetch() of a
GBK-encoded SSR page, decoded with TextDecoder('gbk') and regex-parsed.
No login, no cookies, no signature. Same family as the existing car-platform
adapters (懂车帝/汽车之家). Two ZOL quirks handled:

• Pages require a desktop UA + a zol referer (a mobile UA gets a 153-byte stub).
• Detail URLs' subcategory segment is cosmetic — /0/<id>/param.shtml
  resolves by product id alone, so param/price only need the id from search.

search dedupes by product id; param strips ZOL's "查看…>" link-label chrome so
only real spec values remain; price maps the platform slug
(brand-mol-jd → 京东, …-tmall → 天猫, …-taobao → 淘宝).

Tests / gates

• 11 vitest cases against frozen real-data fixtures (iPhone 15 = product 1427365).
• tsc --noEmit clean.
• check:silent-column-drop new=0, check:typed-error-lint new=0 (no baseline edits).
• doc-coverage --strict 172/172 (docs/adapters/browser/zol.md added).
• Verified live against phones (iPhone 15) and laptops (ThinkPad X1).

Reviews/评测 and 口碑 are intentionally left out of this first cut (separate pages,
can be added later).

Broadened the adapter from 3 → 6 commands (matching the sibling 懂车帝 adapter's breadth):

• koubei <product> — user reviews (口碑): 0–5 star score + 续航/拍照/性能/外观 subscores + body snippet + review link
• pic <product> — product image gallery (外观图/细节图 URLs, imgwrap-anchored, deduped)
• rank [category] — hot-product boards from top.zol.com.cn (手机/笔记本/显示器/空调/相机); the discovery counterpart to search, surfacing product ids with no keyword

All PUBLIC fetches — login adds nothing for a read adapter (ZOL gates only write/personalized features: posting reviews, 收藏, 关注, forums; none are reproducible public data). koubei/pic reuse the productId-only /0/<id>/… form (301→canonical subcat, fetch follows).

Gates: 18 vitest cases (frozen fixtures) · tsc clean · silent-column-drop & typed-error-lint new=0 · doc-coverage 172/172. Verified live.
