Code Review
This pull request addresses a bug in the runRstestCli end-to-end test helper, ensuring that environment variables are correctly unset in child processes. The modification to set the environment variable key to undefined instead of deleting it is the correct approach to handle how tinyexec and Node.js's child_process module manage environment variable inheritance. The change is well-documented with a clear comment explaining the rationale, leading to a more robust and reliable test setup.

Pull request overview
This PR fixes a bug in the runRstestCli helper function where environment variables were not being properly unset in spawned CLI processes. The issue occurred because tinyexec internally merges environments as { ...process.env, ...options.env }, so simply deleting keys from the options object was insufficient when the parent process had those variables set.
Changes:
- Modified environment variable unsetting logic to use
undefinedassignment instead of key deletion
