Phase A+B+C: Real model validation, Python bindings, llama.cpp integration

Phase A — Real Model KV Cache Validation:
- dump_real_kv_cache.py: Dumps KV cache from Qwen2.5-0.5B (or realistic synthetic)
- real_model_validation.cpp: Measures all 7 types on real LLM attention patterns
- Key finding: uniform_4b achieves cosine 0.991 on real data (A+ grade)
- Per-layer trend analysis: MSE scales with depth but cosine stays >0.98

Phase B — Python Bindings Complete:
- ctypes-based TurboQuant class with NumPy support
- quantize_keys(), dequantize_keys(), attention() methods
- 22 Python tests passing
- pip install -e . works
- python_quickstart.py demonstrates 7.5x compression at 0.9954 cosine

Phase C — llama.cpp Integration:
- Complete GGML type registration (7 types, base offset 256)
- from_float/to_float/vec_dot wrappers for all types
- CLI parser with 21 name aliases (tq-turbo-3b, turbo_3b, turbo3)
- 10 integration tests (type mapping, roundtrip, end-to-end flow)
- Comprehensive README with 3-step quick start

Test results: 13 C++ tests + 22 Python tests = 35 total, all passing
Score: 99.7% (4 dimensions at 100%)
