Module graph_builder 

Cpp GraphBuilder implementation for code graph construction.

Extracts Cpp-specific relationships:

• Class definitions (regular, template, sealed, objects, companion objects)
• Function definitions (regular, virtual, inline, extension functions)
• Call expressions (regular calls, method calls, extension calls)
• Inheritance (class/struct inheritance via Inherits edges)
• Interface implementation (Implements edges for classes implementing pure virtual interfaces)
• FFI declarations (extern “C” blocks via FfiCall edges)

Multi-Pass Strategy

1. Pass 1: Extract class/object definitions → Create Class nodes
2. Pass 2: Extract function/property definitions → Create Function nodes
3. Pass 3: Extract call expressions → Create Call edges
4. Pass 4: Extract FFI declarations → Create FFI function nodes
