DESCRIPTION:
    Installs and configures a complete development environment using chezmoi
    dotfiles management. This script will:

    • Install chezmoi if not present
    • Set up prerequisites (Homebrew, Node.js, development tools)
    • Install platform-specific packages (Arch, Flatpak, Homebrew)
    • Configure development applications (VS Code, Zed, Claude Code)
    • Set up Bitwarden integration for secrets management
    • Apply dotfiles configuration templates

OPTIONS:
    --debug           Enable debug mode with verbose output and bash tracing
    --user USERNAME   Set username for Bitwarden Apple ID lookup (default: ashebanow)
    --help            Show this help message and exit

EXAMPLES:
    $0                      # Normal installation (uses 'ashebanow' user)
    $0 --user john          # Installation using 'john_apple_id' Bitwarden entry
    $0 --debug              # Installation with debug output
    $0 --help               # Show this help
