Asset CleanUp Pro v1.2.8.3

* **New:** Added "Alternative Assets" to the CSS/JS Manager. Create and edit lighter alternatives for CSS and JavaScript assets that still need to load, choose where the alternatives are used, and compare their sizes without modifying the original source. * **Improvement:** Reduced redundant processing during Combine CSS/JS cache validation and avoided unnecessary cache rebuilds when separate inline JavaScript, JSON content, or CSP nonce values change. * **Improvement:** Import/Export preserves Pro settings and rules when transferred through Lite, ready for use after upgrading to Pro. * **Fix:** Improved Combine CSS/JS reliability, including asset ordering, cache invalidation, regeneration of missing combined files, and homepage cache cleanup. * **Fix:** Improved JavaScript combining and BODY defer handling to preserve script execution order and existing defer behavior while safely applying defer to eligible BODY scripts.
