Collect real adoption evidence for the Chinese Windows fork

[Lkkisme]

This issue tracks real adoption evidence for Lkkisme/Cap without borrowing upstream Cap metrics.

Current evidence source: https://github.com/Lkkisme/Cap/blob/main/docs/adoption.md

Checklist:

• Update fork stars, forks, watchers, and release downloads after each release.
• Record public user issues and support reports when they appear.
• Keep upstream Cap metrics separated from fork metrics.
• Add user feedback only when it is public or approved for documentation.
• Do not estimate active users from repository views or private messages.
