Allow enums, extensions, and mixins to use `;` as their body and represent that form explicitly in the AST. The parser now produces `EmptyEnumBody` or `EmptyClassBody` for the empty form. Also replace `LibraryIdentifier` with token-based `DottedName` and store the full token sequence for dotted names. This preserves periods and source offsets directly in the AST, which keeps printing, selection, and directive name handling working with the new shape.
