Shell completion generates scripts for `ocm` instead of `ocm-aus`

Issue: Shell completion generates scripts for ocm instead of ocm-aus

Description

The command ocm-aus completion <shell> is intended to generate shell autocompletion scripts for the ocm-aus binary. However, the resulting output currently generates completion logic for the ocm command instead. This prevents autocompletion from functioning correctly for ocm-aus users.

Steps to Reproduce

1. Open your terminal.
2. Run the completion command for your preferred shell (e.g., zsh):

ocm-aus completion zsh

Environment

• Binary: ocm-aus
• Version: aus CLI 0.9.0, commit ef6a2ab
• OS: Fedora Linux 43
• Shell: zsh
