Separate home dirs for each integration test

Details

Previously, all integration tests shared the same home dir which meant that extensions installed in one test, could interfere with another test.

Summary of Changes

Hello @scidomino, I'm Gemini Code Assist[^1]! 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 PR introduces a significant improvement to the integration test infrastructure by establishing distinct home and working directories for each test run. This architectural change within the TestRig class ensures that tests are executed in a highly isolated environment, preventing cross-contamination of configurations and data. The update involves modifying how test files are created and how commands are executed, directing them to the new "workDir" and setting the HOME environment variable to "homeDir", thereby enhancing the reliability and predictability of integration tests.

Highlights

• Test Environment Isolation: Integration tests now operate with a dedicated, custom home directory ("homeDir") and a separate working directory ("workDir"), both created within the main "testDir" for each test run.
• TestRig Refactoring: The TestRig class has been updated to manage these new directory structures, ensuring that test-related files and command executions correctly utilize "workDir" and "homeDir".
• Enhanced Robustness: This change prevents tests from inadvertently affecting each other's configurations or relying on system-wide settings, leading to more reliable and reproducible test results.
