[cayasde]

Summary

• Render module classes and detected test suites without invoking Lune or Open Cloud.
• Run formatting, typechecking, and the full release test suite in pre-commit.
• Add a minor Changeset for the new command.

• sh -x .husky/pre-commit
• Built binary: lutest debug bundle --runtime roblox
