   …A-5048 UTF-16/UTF-32 fixes
   
   From the bot:
   
   ```
   MojibusterEncodingDetector's statistical stage is a hashed byte n-gram model
     (HNG2, int8 tables, even/odd column channels, mean+max pooling, one hidden
     layer), trained on gold v1.12, with UTF-16LE/BE, UTF-32LE/BE and binary
     classes. Runner-ups within 1.0 logit become candidates (calibrated on the 
full
     chain). The UTF-16 specialist, its gate and the shortcut that hid UTF-32 
are
     removed; a surrogate pair cut at the probe end no longer vetoes UTF-16; C0
     controls no longer pass as pure ASCII. Scoring is JIT-friendly and stops 
early
     on long probes once the top class leads by 2 logits (dense-script latency
     within ~1.5x of the old chain). Removes NaiveBayesBigramEncodingDetector,
     nb-bigram.bin and its trainer.
   ```
