Subject: [PATCH 1/2] feat(ui): add keyboard navigation and focus states for
 code blocks

Added `tabindex="0"` to all `<pre>` blocks in Javadoc via `pom.xml` script to allow keyboard-only users to focus and scroll horizontally. Also added a `pre:focus-visible` CSS rule in `custom-javadoc.css` to display an accessible focus ring when code blocks are navigated via keyboard.
