Module pipeline 

Layered processing pipeline for C source code

This module provides a multi-stage processing pipeline that transforms C source code to make it more parseable by tree-sitter, while preserving semantic information.

Pipeline Stages

1. Platform Detection - Identify target platform (Linux, FreeBSD, Darwin)
2. Header Stub Injection - Inject type definitions for known headers
3. Conditional Evaluation - Strip #if 0 blocks, optionally evaluate simple conditions
4. GCC Neutralization - Remove/replace GCC extensions
5. Attribute Stripping - Remove platform-specific attributes

After these stages, the code is ready for tree-sitter parsing.
