Pull Request Overview
This PR adds an implementation for bool on the MetaType so that truthiness for types is evaluated using nb_bool rather than len.
- Added nb_bool implementation in MetaType.cs that always returns 1.
- Updated native type offsets (TypeOffset.cs and ITypeOffsets.cs) to include nb_bool.
- Introduced embed_tests to verify that types are truthy in Python.
