[BUG] IPv6 address not working

[Myzel394]

Describe the bug

Using an IPv6 address always shows this error:

ERROR: Invalid SSH address format. Expected format: [USER@]HOST[:PORT]

I tried in several formats such as:

docker pussh myimage root@fe80::ab:1f:a1:2a11
docker pussh myimage root@[fe80::ab:1f:a1:2a11]
docker pussh myimage 'root@[fe80::ab:1f:a1:2a11]'

How to reproduce

pussh to a server with an IPv6 address

Expected behavior

Should work

Environment:

• Unregistry versions
  • pussh version (output of docker pussh --version): docker-pussh, version 0.1.0
  • unregistry (Docker image) version:
• OS version: macOS
• Bash version (output of bash --version): GNU bash, version 3.2.57(1)-release (arm64-apple-darwin24) Copyright (C) 2007 Free Software Foundation, Inc.
