docs: standardize Chinese documentation and fix broken links

docs: standardizing Chinese documentation to README.zh.md

Overview

This PR aims to standardize the Chinese documentation naming convention and fix minor broken links in the README files.

Changes

• Added README.zh.md: Renamed/Migrated from README_CN.md (while keeping both for compatibility if needed, but updated all internal references to use the standardized .zh.md extension). This follows GitHub's common practice for automatic language detection.
• Fixed broken links: Corrected a typo in the last-commit-shield-link (changed commcommits to commits) which was causing the "Last Commit" badge link to be broken in the Chinese version.
• Updated language switchers: Synchronized the language selection links across README.md, README.zh.md, and README_JA.md to point to the new README.zh.md.

Why this matters

1. Consistency: Using the .zh.md extension aligns with community standards and improves discoverability for developers using localized GitHub settings.
2. Maintenance: Fixing the broken commit badge link ensures a professional and high-quality presentation for users interested in project activity.
3. Navigability: Unified language links across all README variants provide a seamless switching experience.

The standalone -- line looks like an accidental typo (likely intended to be a Markdown horizontal rule ---). As-is it renders as plain text and breaks the section formatting.

This link targets examples/openclaw-plugin/README.zh.md, but that file does not exist in the repo (only README_CN.md / README.md are present). This will render as a broken link; either add the README.zh.md file in that directory or update the link to an existing localized README.

This link targets examples/opencode-memory-plugin/README.zh.md, but that file does not exist (the directory currently has README_CN.md / README.md). Please update the link to an existing file or add the missing README.zh.md to avoid a broken reference.

This link points to bot/README.zh.md, but the bot/ directory currently contains README_CN.md / README.md and no README.zh.md. This will be a broken link unless the file is added or the link is updated to the correct target.

Thanks a lot for taking the time to improve the docs and clean this up.

After reviewing it, we’re going to keep the current README naming/layout for now, so we won’t move forward with introducing README.zh.md in this repo at this stage. The broken link fix is appreciated, but overall this PR would also introduce an additional top-level README variant that we’re not planning to maintain right now.

I’m going to close this PR for now, but we really appreciate the contribution and your attention to detail. Thanks again.
