When you run replace-username.sh it doesnt replace home-nixuser.nix with home-yourusername.nix

[rudra-code-creator]

solution:

1. Manually rename replace home-nixuser.nix to home-yourusername.nix under /modules/users/youruser
2. Update flake.nix with new path

In case anyone is having this issue as well
