68f74182 - Use test contexts for tool directories (#21110)

Use test contexts for tool directories (#21110) Tool integration tests repeatedly configure the same isolated tool and executable directories on every command. Add an opt-in `TestContext::with_tool_dirs` builder for these directories and use it throughout the uninstall tests, preserving their existing paths, explicit `PATH` override, and snapshots.
