TheTomandClaude Opus 4.6 e1d4ff8d23 docs: add NIAH/KLD quality validation — asymmetric mandatory for dense models
Symmetric turbo4 is catastrophic on dense models (KLD=6.86, NIAH 0/15).
Asymmetric K=FP16 fixes everything (KLD=0.003, NIAH 15/15, top-1 98.1%).

Tested on Qwen2.5-7B-Instruct-8bit (28 layers, all KV cache).
Quality test suite added: scripts/mlx_quality_suite.py
