新增登录态失效与微信公众号外链缺失两类发布错误归一化，
将原本散落在适配器里的中文提示集中到 shared/publisher-errors，
让渲染层与 main 进程共用同一份用户可读文案。

Inject the YiDun guardian client to obtain ursToken without relying on
window.neg, fetch the publish detail (wemediaId/onlineState/...) before
saving drafts so 100002 "参数错误" stops blocking submit, downgrade
markdown tables to paragraph rows like Baijiahao, and surface friendlier
errors for token, draft and publish-click failures.

- Detect qiehao's real-name auth blocking response (code/message) in the
desktop adapter, surface a Chinese-friendly summary, and propagate the
detail through the failure result.
- Extract a shared publisher-errors module so the renderer can normalize
these messages for the publish task table without duplicating regex.
- Pre-process article HTML for qiehao before upload via a new
packages/publisher-platforms/src/qiehao.ts entry point.
- Update the manual self-test notes for jianshu and qiehao with the
latest results.
