Add the OmniRef (Ref2VA, VSA tile 128) and V2/V2.1 Consumer (T2VA,
VSA tile 64) profiles of one quantization-aware distillation recipe:
NVFP4 W4A4 q/k/v/out and FFN linears in all 50 blocks, the FP4
sparse-attention emulator, frozen VSA gates and norms, output plus
layer-reconstruction regression against a frozen bf16 teacher, and
best-by-score checkpoints with audio eligibility guards.
Training code: the PDD-QAD method, the two H3 model plugins, the
NVFP4 emulated linear, and the tile-64/128 Triton emulator with its
PyTorch numeric reference. The VSA attention impl gains a fine
attention override hook and lets tile 128 run grad-capable forwards
through it. The trainer gains opt-in tagged checkpoints and early
stop hooks for the QAD guards.
Also add two runnable configs, the training guide, and CPU/GPU tests.
