This commit introduces C API bindings for AIG LongestPathAnalysis, enabling timing analysis of And-Inverter Graph circuits from C and other languages. Key additions: - AIGLongestPathAnalysis and AIGLongestPathCollection opaque handle types - aigLongestPathAnalysisCreate/Destroy for analysis lifecycle management - aigLongestPathAnalysisGetAllPaths for retrieving timing path collections - aigLongestPathCollectionGetSize/GetPath for accessing individual paths - LongestPathCollection C++ class for efficient path storage and sorting - Comprehensive C API test suite with multiple test scenarios The API uses JSON serialization for path data exchange, providing a stable interface while the underlying data structures evolve. Paths are automatically sorted by delay in descending order for efficient critical path analysis.

This commit introduces C API bindings for AIG LongestPathAnalysis and LongestPathCollection, enabling longest path analysis of AIG circuits from C and other languages.
The API uses JSON serialization for path data exchange, providing a stable interface while the underlying data structures evolve. Paths are automatically sorted by delay in descending order for efficient critical path analysis.
