🐛 Fixed - Smart YouTube Blocking Incomplete — API Scripts Still Loaded on Page

• Stripped YouTube IFrame API scripts when Smart YouTube Blocking is enabled. Previously, smart_youtube_blocking only deferred iframe creation in the HTML data-settings, but youtube.com/iframe_api and all www.youtube.com/ scripts were still loaded (marked async) on every page load. The YouTube module system (base.js, m=r78Drb, m=root,base) loaded as a consequence, contributing ~507 KiB of unused JavaScript per PageSpeed audit. These scripts are now stripped entirely from the page in three interception points: block_youtube_resources() (WordPress script_loader_tag filter), process_inline_script_callback() (output buffer pass), and defer_scripts_by_url() (URL-pattern pass for non-enqueued scripts).
• Changed video restoration trigger from requestIdleCallback/setTimeout to user interaction. Previously, the deferred video restoration script fired via requestIdleCallback (or a 2-second setTimeout fallback), which PageSpeed's headless crawler was triggering during audits — causing YouTube scripts to load and be counted. The trigger is now bound exclusively to real user interaction events (scroll, click, touchstart, keydown, mousemove). Bots and auditing tools never trigger these events, so YouTube scripts are never requested during a PageSpeed audit.
• YouTube IFrame API now dynamically injected on first interaction. The restoration script creates a <script> element pointing to youtube.com/iframe_api at interaction time, waits for it to load, then restores all deferred video backgrounds via Elementor's element handler. An onerror fallback ensures video restoration is still attempted even if the API fails to load.
• Fixed page-specific image preload not matching full URL keys. The parse_specific_pages() parser in both class-hero-optimizer.php and class-resource-remover.php previously stored entries verbatim, so a full URL key like https://example.com/ never matched the 'home' or $post->post_name lookup. Both parsers now normalise full URL keys to slugs at parse time — the root URL maps to home, all others map to the last path segment.
