WordPress Performance Tweaks

== Description ==
Simple but effective performance tweaks for WordPress—now with a polished, tabbed settings UI.

* CF7 reCAPTCHA Smart Loader — Dequeues reCAPTCHA when no CF7 form is present.
* Disable Advanced Custom Fields on Frontend — Stops ACF assets from loading on the frontend.
* Emoji Unloader — Removes Emoji CSS and JavaScript.
* Defer JavaScript — Adds defer attribute to eligible scripts.
* Async JavaScript — Adds async attribute to eligible scripts.
* Async/Defer Exclude Handles — A textarea to exclude script handles from async/defer.
* Remove Query Strings — Strips ?ver= from CSS/JS URLs to improve CDN caching.

* Separate Core Block CSS (WP 5.8+) — Opt-in to load only the CSS for blocks used on the page.
* Disable Dashicons for Visitors — Removes dashicons for non-logged-in users.
* Disable jQuery Migrate (frontend) — Drops jquery-migrate from frontend dependencies.
* Boost Hero Image (fetchpriority) — Adds fetchpriority="high" to the first content image on singular pages.
