Add C++ RTTI extraction

[Veryyes]

Summary

• Adds `ClassInfo` and `VTableEntry` Pydantic primitives to represent recovered C++ class metadata (vtable layout, inheritance, virtual/multiple inheritance flags)
• Implements `get_classes()` in the Ghidra (dragon/pyghidra), Rizin, and Binary Ninja backends, populating `Binary.classes` with demangled class names, vtable addresses, vtable entries, and base/derived class relationships
• Adds `binocular/rtti_util.py` with a shared Itanium ABI name decoder used by all three backends
• Adds three test C++ binaries (`rtti_simple.cpp`, `rtti_inherit.cpp`, `rtti_diamond.cpp`) covering single, single-inheritance, and diamond-inheritance scenarios
• Adds `test/test_rtti.py` with test suite covering Ghidra, Rizin, and Binary Ninja RTTI extraction

Test plan

• `cd test && make` to build the RTTI test binaries
• `pytest test/test_rtti.py` passes for all installed backends
• `pytest test/` — full suite passes with no regressions
• Verify `Binary.classes` is JSON-serializable (Pydantic round-trip)
