Following from the discussion on #28:

On Ubuntu 22.04, I also had issues running aftman self-install without sudo. Without running as sudo I get this error:

./aftman self-install
[INFO  aftman::tool_storage] Updating all Aftman binaries...
[INFO  aftman::tool_storage] Updated Aftman binaries successfully!
[ERROR aftman::system_path::unix] Error trying to write /home/overhash/.zshenv: failed to open file `/home/overhash/.zshenv`

What's more interesting is that when I do use sudo ./aftman self-install, it still won't update the zshenv. I had to manually move my .zshenv to a new file and then run aftman self-install (which created a fresh ~/.zshenv) before I merged my old changes in.

Most interestingly, all files are chmod 644. Running aftman self-install again after installing still causes the issue. I'm suspecting there's something funny going on here when actually reading the file.
