HGW Better internal link search for Block editor

HGW Better internal link search for Block editor improves the default internal link search inside the block editor by adding a post type or category selector to the link popup.
This allows editors to narrow down search results to specific post types such as Posts, Pages, or custom post types.

Features

• Adds a clean “post type and category filter” dropdown above Block editor link search results.
• Works with all REST-visible and publicly queryable post types.
• No database queries or custom endpoints — fully uses WordPress core APIs.
• Loads only inside the editor, never on the front-end.
• Lightweight, fast, and compatible with all major themes and plugins.
