```
perf(netflow-db): raise only distinct weighted masses and spread q values across threads

Weighted structure maps each moment's masses to indices into the sorted distinct masses, so every q computes one powf per distinct mass. Structure rows for different q values are independent and now run in parallel on the caller's rayon pool. Output stays byte-identical: unweighted on the fixtures and 20 real windows, weighted on 42 packet, byte and IPv6 inputs.

```
