mise install can't cope with symlinked directories

[aug24]

I'm implementing a devcontainer setup and trying to avoid duplicate downloads for people with slow internet access.

I have a shared cache at /installs which is mounted across several containers. The /download directory is local to the machine. As a result the rename command fails, because the download is on a different filesystem. Mise should fallback to a move instead of a rename.

For now, I have resolved the issue by putting the /download directory on the same filesystem as the /installs directory, but this should not be necessary.
