test(test-tool): uninstall all versions and clear cache before installation

[jdx]

Summary

• Modified mise test-tool to uninstall all existing versions and clear cache before testing
• Added e2e test to verify the new behavior

Details

This ensures a clean state when testing tools by:

• Uninstalling all existing versions of the tool
• Clearing the backend cache directory
• Then performing a fresh installation and test

This helps ensure tests are reproducible and not affected by previous installations or cached data.

Test plan

• Added e2e test test_test_tool_clean to verify the cleanup behavior
• Verified existing test-tool functionality still works

[nitpick] These debug statements appear to be leftover from development. Consider removing them as they don't add value in production and the information is already available through other logging.

Suggested change

debug!("Tool short name: {}", tool.short);

[Copilot]

The version is cloned twice unnecessarily. Consider using version.clone() only once and reusing it, or restructure to avoid the extra clone in line 173.

Bug: Cleanup Fails, Report Incomplete

The cleanup logic only removes directories for the main tool, not its dependencies, which can lead to inconsistent test states. Also, if any directory removal fails, the progress report's finish() method is skipped, leaving the report unfinished and potentially causing UI issues.
