fix(quantizer): use rounded int8 values for SQ8 metadata to fix recall drop ( #329 )
...
fixes #328
Problem:
SQ8 metadata (squared_sum, sum) was computed from pre-rounded float
values, causing mismatch with actual stored int8 values. On asymmetric
datasets (e.g. OpenAI 1536D where |x_min| >> x_max), this leads to
severe recall drop.
Solution:
Move std::round before accumulating squared_sum and sum.
