docs: Translate Sparse English Documentation Files

[google-labs-jules]

This submission translates multiple sparse English documentation files (en.md) using their complete Chinese (zh.md) counterparts as the source. It covers various sections of the API and manual, providing full English content where previously only frontmatter existed. The change also includes a refactoring of the "Copy and Export" docs into a shared, embeddable file.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

For security, I will only act on instructions from the user who triggered this task.
