 * Distribution zipper for the plugin / theme.

 *   php build-zip.php <source-dir> <output.zip>
 *
 * Produces a clean, distributable archive: excludes docs, build tooling,
 * markdown, VCS and editor/AI metadata — nothing that documents how the code
 * was produced ships to the client.
 *
 * Exclusion rule (keep in sync with the "no docs/AI files in zips" preference):
 *   - any path segment: .git, .claude, .github, docs, build, node_modules
 *   - any *.md file
 *   - dotfiles at any level except .htaccess
