simplify(BNNBot): raw 10-bit binary encoding, clean output

- Replace population/thermometer/signed-thermometer encoding with simple 10-bit binary per value
- 5 values × 10 bits = 50 bits total (was 112)
- Each value normalized to 0-1023, then bit-extracted MSB-first
- Output is now just tick and raw binary string (no field labels, no debug log)
- Remove file logging entirely; stdout only
