Usage: omarchy dev pkg-test [package-name] [path-to-checkout]

Builds and installs an Omarchy package from a local Omarchy source
checkout. Use when changes need to land at fixed system paths (/etc/,
/usr/lib/systemd/, udev rule bodies, plymouth) that omarchy-dev-link
can't shadow.

Defaults:
  package-name      omarchy-settings
  path-to-checkout  ~/Work/omarchy/omarchy-installer

The pkgver of the built package is tagged 'dev.<short-sha>[.dirty]' so
'pacman -Q' makes it obvious where the installed version came from.

PKGBUILDs are read from \${OMARCHY_PKGBUILDS_DIR:-~/Work/omarchy/omarchy-pkgs/pkgbuilds}/<package-name>/.
