"""AGIWSNeuralQuant — Universal neural network quantization library.

Unified architecture: one parameterized Quantizer for all formats,
QuantizedWeight/QuantizedActivation containers, dual-path cross-quantization
distillation, chunked dequant for minimal VRAM, QAT with learnable parameters
via STE, SSM-aware exclusion patterns.

Quantization primitives (pure tensor-level functions, no nn.Module wrappers):
  - ternary (BitNet 1.58): ternarize_tensor, ternary_dequantize, fake_ternarize
  - nf4 (QLoRA): NF4_LUT, quantize_nf4, dequantize_nf4, pack/unpack, double_quant
  - fp8 (E4M3/E5M2): FP8 LUTs, quantize/dequantize
  - fp4 (E2M1 / NVFP4 / MXFP4): FP4 LUT, quantize/dequantize, pack/unpack, E8M0
  - ste (Straight-Through Estimator): STEQuantize, fake_quantize

Layer wrappers live ONLY in base.py (QuantizedModule) — no per-format
nn.Module classes. The unified Quantizer (quantizer.py) + presets (presets.py)
configure all 40+ formats as parameters, not separate classes.
