Summary of Changes

Hello @shaonianche, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the project by integrating code coverage reporting. It adds pytest-cov to the project's dependencies, configures coverage settings, and updates .gitignore to exclude coverage-related artifacts. This will help monitor and improve the test coverage of the codebase.

Highlights

• Code Coverage: This PR introduces code coverage reporting using pytest-cov to track the percentage of code covered by tests.
• Dependency Management: Adds pytest-cov as a development and test dependency, managed via pyproject.toml and uv.lock.
• Configuration: Configures coverage settings in pyproject.toml to specify source files and exclude test/example directories.
• Git Ignore: Updates .gitignore to exclude coverage-related files and directories.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request introduces code coverage reporting using pytest-cov. The configuration changes in .gitignore and pyproject.toml are appropriate for integrating coverage analysis into the project. I have one suggestion to make the file exclusion patterns in the coverage configuration more robust for future changes.
