CoreBoost v3.3.2

✨ Added - LCP Foreground Injection (cb-lcp)

• cb-lcp CSS class convention for Elementor sections. Add cb-lcp to any Elementor section or container's Advanced → CSS Classes field. CoreBoost detects the class in the output buffer and injects an <img fetchpriority="high" loading="eager" class="cb-lcp-img"> as the first child of that element. This gives the browser a native <img> LCP target, bypassing Elementor's lazy-load CSS gate (background-image: none !important until .e-lazyloaded is added by deferred JS).
• Image URL resolved from Elementor data-settings. The injected <img> uses the element's background_video_fallback.url (preferred — the image shown before/during video load) falling back to background_image.url. The <link rel="preload"> emitted by Hero_Optimizer is also updated to prefer the video fallback URL when cb-lcp is present, so preload and LCP element always point to the same file.
• .cb-lcp-img CSS — absolutely positioned, inset: 0, width/height: 100%, object-fit: cover, z-index: 0, pointer-events: none. Sits behind Elementor's overlay (::before) and the video container without interfering with layout or interaction.
• New setting: enable_lcp_foreground_injection — checkbox under Hero Image & LCP Optimization. Off by default.

🐛 Fixed - Remove Unused CSS/JS Pattern Matching

• remove_unused_styles() and remove_unused_scripts() now support the same pattern syntax as CSS/JS defer. Previously both methods did a strict wp_style_is() / wp_script_is() exact-handle lookup, so patterns like widget-, elementor-post-, or swiper (which work in the defer fields) silently matched nothing. The methods now iterate $wp_styles->registered / $wp_scripts->registered and apply the same four-tier matching: exact, trailing-dash prefix, wildcard (*), and partial/contains. Extracted into a shared handle_matches_pattern() helper.
