Pull request overview

This PR merges a comprehensive test suite for C99 data types and type aliasing into the cc compiler project. The changes establish a robust foundation for testing various C type systems including primitives, composites, pointers, and type qualifiers.

Key Changes:

• Added extensive test coverage for C data types (primitives, structs, unions, pointers, arrays, typedef, bitfields)
• Introduced common test utilities for compiling and running C code
• Added parse module structure for AST and parser components
• Integrated cc module into workspace
