- The nix.mount drop-in is also removed when the uninstall fails or is
interrupted (exit trap), and when daemon-reload failed after writing it.
- --dir with a trailing slash no longer puts the temporary clone inside
the directory it replaces.
- The template's repository uses Nix's git when SteamOS has none, so the
template marker exists there too (--clone needs it).
- A failed Nix uninstall during the reinstall of a broken Nix says so.
- clone_config: one branch per case; shorter comments, help and docs.
- Tests: an interrupted uninstall, --dir with a trailing slash; a
redundant "used as it is" case dropped.
