feat(publish): handle qiehao real-name auth via shared publisher errors

- 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.
