Add latest build ZIP file, download button in README, and version history tracking

### Feature Request

To streamline publishing to the Chrome Web Store and improve version management:

1. **Add Latest Build ZIP**
- Include the latest production-ready ZIP file of the extension in the repository (e.g., under `/release/latest.zip`).
- This will allow the production team to easily access and push the latest build to the Chrome Web Store.

2. **README Download Button**
- Update the README file to add a clear button or link for downloading the latest ZIP build.
- Example markdown:
```markdown
[](./release/latest.zip)
```

3. **Version History Tracking File**
- Add a new file (e.g., `VERSION_HISTORY.md` or `CHANGELOG.md`) to log version updates in the following format:
```
1.0.0 -> Initial release
1.0.1 -> Bug fixes
1.1.0 -> Feature update
2.0.0 -> Major release
```

This will improve clarity for both production and users, and help with tracking releases and updates.

**Suggested next steps:**
