Git Operations Examples

# Example: Authenticated Git Operations
# Shows how to clone private repositories using tokens and
# SSH keys for authentication.
#
# Authentication methods:
#   Token auth:  auth: { type: token, token: "ghp_..." }
#   SSH:         Use SSH URLs (git@github.com:org/repo.git)
#
# IMPORTANT: Never hardcode tokens in workflow files.
# Use --var flags or environment variables instead.
