Usage: $0 <package> [OPTIONS]

Create pkgbuilds/<package> with Omarchy metadata. AUR packages are synced
immediately after metadata is written.

Options:
  --source <aur|local>       Package source (default: aur)
  --local                    Shortcut for --source local
  --aur <name>               AUR package name when different from local directory
  --no-sync                  For AUR packages, mark sync disabled after initial setup
  --fast                     Put package in the fast release ring
  --release-ring <ring>      Release ring (currently: fast)
  --scaffold                 For local packages, create a starter PKGBUILD
  --force                    Overwrite existing .omarchy/package.json
  -h, --help                 Show this help message

Examples:
  $0 yay
  $0 spotify --fast
  $0 signal-desktop --no-sync
  $0 omarchy-zsh --local --scaffold
