3 people c819477692 Add block-size experiment paper and update docs ...

Block_size=128 achieves 5.12x compression (vs 4.57x at 32) with
identical PPL across all tested Metal paths: asymmetric q8_0-K +
turbo{2,3}-V, symmetric turbo3/turbo3, and Boundary V (LA-V7).
Validated on 3 architectures (dense, Qwen, hybrid MoE), 3 context
lengths (512, 8K, 32K), and 2 hardware platforms (M5 Max, M2 Pro).

M2 Pro showed +3-7% decode improvement on tested 1.5B model.
No speed regression on M5 Max.

Also fixes pre-existing flaky d=192 turbo4 test threshold (0.6 -> 0.7).

Credit to @AmesianX whose block_size=256 implementation prompted
the investigation.
