Subject: [PATCH] fix: Filter out script/style tags during DOM tree build

Previously, script and style tags were only filtered during render,
but their text content (JavaScript code) was still in the DOM tree.
Now we skip these tags entirely during DOM tree construction,
resulting in much cleaner output for modern websites.
