#   /bin/bash -c "$(curl -fsSL --max-time 60 https://raw.githubusercontent.com/elastic/support/main/bootstrap-mac.sh)"
#
# Or with custom GITDIR:
#   GITDIR=~/code /bin/bash -c "$(curl -fsSL --max-time 60 https://raw.githubusercontent.com/elastic/support/main/bootstrap-mac.sh)"
#
# Options: -d|--debug  Enable debug logging; -h|--help  Show usage
#
# This script will:
#   1. Install Xcode Command Line Tools (if needed)
#   2. Install Homebrew (if needed)
#   3. Install GitHub CLI (gh)
#   4. Authenticate with GitHub (interactive)
#   5. Clone the elastic/support repository
