scaffold child-theme: add RTL stylesheet support via wp_style_add_data()

[Copilot]

wp scaffold child-theme enqueued parent and child stylesheets but never registered RTL variants, leaving RTL language sites without proper stylesheet direction switching.

Changes

• templates/child_theme_functions.mustache: Add wp_style_add_data( $handle, 'rtl', 'replace' ) after the child theme's wp_enqueue_style() call so WordPress automatically loads the -rtl.css variant when text direction is RTL. The parent theme's style is not given RTL data since its structure is unknown.

Generated functions.php now looks like:

function my_child_parent_theme_enqueue_styles() {
    wp_enqueue_style( 'parenttheme-style', get_template_directory_uri() . '/style.css', array(), '0.1.0' );
    wp_enqueue_style(
        'my-child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array( 'parenttheme-style' ),
        '0.1.0'
    );
    wp_style_add_data( 'my-child-style', 'rtl', 'replace' );
}

• features/scaffold.feature: Assert the wp_style_add_data call is present for the child theme style in the generated functions.php.

Pull request overview

This PR updates the wp scaffold child-theme output so generated child themes declare RTL support for their enqueued stylesheet via wp_style_add_data(), and adds a Behat assertion to ensure the generated functions.php includes that RTL metadata.

Changes:

• Add wp_style_add_data( $child_handle, 'rtl', 'replace' ) to the child theme functions.php template.
• Extend the scaffold Behat feature to assert the RTL metadata call is present in generated functions.php.
