Adds the no-navigation `quickCheck` to each adapter's
registerSiteAuthCommands config so `opencli auth status` (PR #1879) resolves
login state in quick mode (CDP getCookies, no per-site goto) instead of
reporting `unknown`.
- quickCheck reuses each adapter's existing poll cookie gate (has<Site>Cookie),
which is a logged-in-only, no-nav check returning boolean.
- Deliberately NOT wired (stay `unknown` in quick mode, available via --full):
- gitee/hf/deepseek/quark/reuters/zsxq: no reliable logged-in cookie; they
detect via no-nav fetch / localStorage / Bearer which need the site origin.
- doubao/ke/coupang/manus: session cookie is present for anonymous users, so a
cookie quickCheck would false-positive — `unknown` is more honest.
Live: auth status --site resolves logged_in/not_logged_in for cookie-gate sites
(v2ex/github/zhihu/claude/taobao/twitter/bilibili) in quick mode; excluded
sites report unknown. Audits new=0/new=0; suite 5054 passed.
