Pull Request Overview

This PR refactors the pseudo selector handling by splitting Pseudo into two distinct types: PseudoElementSelector for pseudo-elements (::before, ::after, ::marker) and PseudoClassSelector for pseudo-classes (:hover, :first-child, etc.). Additionally, it introduces support for generating pseudo-elements in the layout builder and adds a rule indexing system to optimize selector matching.

• Separated pseudo-class and pseudo-element selectors into distinct types
• Added pseudo-element generation support in the layout builder with proper content handling
• Moved style rule lookup logic from rules.cpp to a new rules-index.cpp file
• Updated all selector matching to support pseudo-elements as a parameter

Corrected spelling of 'maker' to 'marker'.

A small step for the dev but a great step for paper-muncher
