Ipsum passes PHPStan at the level 5 the repository configures, but has 69 errors at level 10. This fixes all of them, so Ipsum is clean at level 10 with bleedingEdge, as Twenty Twenty-Four and Twenty Twenty-Five already are.

• Pattern image URLs. Thirteen patterns appended the theme version as a cache busting ?ver= (added in Rename the theme functions and add the theme version to pattern images ipsum#163 in response to review of Add Ipsum, the new default theme for 7.2 #14558), reading it with WP_Theme::get( 'Version' ), which returns string|false. That accounted for 60 of the errors. A new ipsum_get_asset_url() helper takes a path relative to the theme, resolves it with get_parent_theme_file_uri(), and adds the parent theme version with add_query_arg() when it can be read. The patterns now call it. Going through get_parent_theme_file_uri() also makes each asset URL filterable with parent_theme_file_uri, which the patterns' plain get_template_directory_uri() concatenation did not allow, and the ver is added after that filter runs, so a filtered URL keeps the cache busting.
• Stylesheet version. ipsum_enqueue_styles() loads the parent theme's style.css but versioned it with the active theme, so with a child theme active, an Ipsum update did not change the stylesheet URL. It now uses get_template(), matching the pattern images and Twenty Twenty-Four.
• Comments call to action binding. The postId context is untyped and its get_the_ID() fallback can be false. The post is now resolved with get_post(), which falls back to the current post as before, and the callback returns null when there is none, so the block keeps its original content. The unused $source_args, which must still be accepted to reach the block instance, is unset.
• Search block ARIA label support. The block supports are narrowed to an array before ariaLabel is added.
• Iterable value types for the block binding args, the template types and the block metadata.

Native types were left off the hook callbacks' parameters, since a plugin filtering in a non-array would otherwise cause a fatal error.

The theme's assets/images/ (and assets/fonts/) directories are missing from the import, so pattern images are currently broken regardless of this change. That is being addressed separately.

Trac ticket: Core-66352

Testing Instructions

1. Run vendor/bin/phpstan analyse -c phpstan.neon.dist --level=10 src/wp-content/themes/ipsum. No errors are reported, where trunk reports 68 (69 with bleedingEdge, which also reports the unused $source_args).
2. Activate Ipsum and insert the Gallery Offset and CTA Membership patterns in a post. Image URLs are built from the theme directory and end in ?ver=1.0.
3. With a child theme of Ipsum active, the ipsum-style stylesheet URL ends in Ipsum's version, not the child theme's.
4. View a single post using a template with the comments call to action. The link reads "Be the first to comment" or "Join the conversation" depending on the comment count.
5. In the Site Editor, a Search block offers an ARIA label setting.

This is important because get_parent_theme_file_uri( 'style.css' ) only ever refers to the parent theme's style.css, but without passing get_template() here, then it defaults to the child theme.
