v2.1.1 — pre-quantized repo param fix

fix: parseHfConfig under-counted params ~2x for pre-quantized repos (MLX/AWQ/bnb) by deriving bytes from torch_dtype instead of the stored bit-width. Now reads quantization(.bits)/quantization_config(.bits) first. Reported with measurements and a suggested fix by @gilbert-barajas (#2) — thank you. Also: first measured fixture recorded (#1), README: registry listings + agent HTTP API + CC0 census (HF Dataset/Space).
