解析链接令牌失败

Error message

解析链接令牌失败: %w

What it means

json.Unmarshal failed on the ting77 token endpoint body despite a 200. The endpoint returned non-JSON (challenge page) or a changed schema for tokenResponse. Distinct from status-code and rate-limit errors, which are checked before this.

Solutions

1. Dump the body to identify HTML interstitials
2. Update tokenResponse if the JSON shape changed
3. Retry once for transient garbage responses
