swap-stack: ornith duo 128K via mixed KV (q8 K + turbo2 V); turbo-KV root cause

Probe matrix proved K is the broken side of turbo KV on Qwen3-4B
(QK-norm gamma outliers vs PolarQuant's no-per-channel-range format)
while V tolerates 2-bit for free. Applied to ornith duo main: K q8_0 +
V turbo2 = 128K ctx in ~880MB RAM at full speed (8.7-10.1 t/s concurrent,
vs 3x decode loss with turbo2 K). Qwen duo stays q4/q4 24K — only clean
mix is bigger than q4/q4. InnerQ equalizer confirmed broken as shipped
(compensation error grows with scale strength); documented in
MOE-FINDINGS with the full matrix and fix ladder.
