Feature: Add CLI Auto-Completion (Bash/Zsh)

[chefgs]

Summary

Add shell auto-completion for DevOps-OS CLI

Why

The CLI already has many commands (process-first, scaffold gha, scaffold gitlab, scaffold sre, etc.). Adding shell completion will improve usability.

Tasks

• Add support for bash completion

• Optionally support zsh

• Document installation in docs site

Example usage:

devopsos scaf<TAB>

Expected result:

scaffold gha
scaffold gitlab
scaffold jenkins
scaffold sre
