Subject: [PATCH] test(tui): cover same-volume cwd outside home

The existing /opt footer case reaches the ordinary outside-home return on POSIX, but Windows resolves it on the checkout drive while the user profile is on another drive. That exercises the cross-drive guard instead and leaves the same-volume fallback uncovered in Windows coverage.

Add the resolved parent of the home directory as a platform-neutral outside-home path. The case now covers the fallback on every host while retaining /opt to exercise the Windows cross-drive path, restoring per-file branch, statement, and line coverage without platform-specific expectations.
