chameleon 4.5.2

Fixed

• Constant paths are extracted portably across prism versions. Ruby 3.3's bundled prism
  (0.19) drops the root anchor from ConstantPathNode#full_name, so a ::Audit reference read
  back as bare Audit and the lexical resolver treated an absolute reference as ambiguous — a
  CI-only failure the local prism 1.9 never showed. The dump now walks the path segments itself
  (keeping the :: anchor on every version) and returns nil for dynamic parents (self::FOO)
  instead of stringifying them.
