Subject: fix(install): use rename-before-unlink on all platforms

Problem: On macOS Apple Silicon, a plain unlink can leave stale code
signature metadata in the kernel cache, causing SIGKILL on next page
fault after `TSUpdate`.

Solution: Apply the rename-then-unlink strategy unconditionally instead
of only on Windows.
