语雀 — two connection modes

The connector injects exactly one credential, and the CLI picks its mode from it:

• $YUQUE_COOKIES — the user's own browser login jar, captured by the ACE extension. Free. Drives 语雀's internal web API.
• $YUQUE_TOKEN — a 语雀 personal access token for the official open API. Requires a paid 语雀超级会员.

Both are secret — never echo, print, log or return them. Every command reports the active mode back as auth_mode; read that instead of guessing.
