Description

The released binary tar contains a ./ directory:

$ tar tvf jj-v0.29.0-aarch64-unknown-linux-musl.tar.gz 
drwxr-xr-x runner/docker     0 2025-05-07 19:38 ./
-rwxr-xr-x runner/docker 28212968 2025-05-07 19:38 ./jj
-rw-r--r-- runner/docker    17771 2025-05-07 19:38 ./README.md
-rw-r--r-- runner/docker    11358 2025-05-07 19:38 ./LICENSE

Unpacking it can possibly change the permissions of the current directory.

E.g., if unpacking as root in /tmp, it will reset /tmp permission to 0755, which has strange effects.

Please either remove that entry in the tarfile, or put everything in a new toplevel directory in the tarfile.
