Pull Request Overview
This PR renames two core QL classes to better reflect their roles, deprecates the old names, and adds helper methods and predicates to navigate between declarations and the entities they declare.
- Rename
DeclaredType→DeclaredTypeEntityandBuiltinType→BuiltinTypeEntity, with deprecated aliases for backward compatibility. - Introduce new methods on
TypeSpec(getDeclaredType,getRhsType) and onFieldDecl(getField,isEmbedded), plus updated docs. - Update library tests to exercise the new helpers and adjust expected outputs accordingly.
