The @ just means the file has extended attributes which can be seen with
xattr.
MacOS is just UNIX underneath, so I don't see why /tmp should not
operate normally. Is there any chance the OP has TMPDIR set to '.'?
Here's a post on /tmp in MacOS that may be illuminating.

Unlike plain Linux systems Apple seems to want to hide its tmp
directories from ordinary users.

As for the latter, I don't think I can be of any help. My own
experience is that these files, whether being preserved or not,
are placed/left in the temporary files directory (/tmp, TMPDIR etc),
which is not expected to be at ~/musicformats-git-dev/files/musicxmlfiles.
And now, looking at the idiosyncratic file listing (I didn't spot the
hyperlink in the text version of the OP, or understand the @ sign),
and a quick Order→From in my MUA, I see that the OP's platform is
likely a Mac Mini M1, whatever that is, so I'll bow out.
