frank-small: Q5_K_M -> Q6_K rung at the held 2x200704 f16-KV shape

The freed third slot funded exact V; the remaining ~3.5 GiB of honest
nvidia-smi free (3,571, not the 4,046 total-minus-used I quoted - the
driver holds ~450 MiB of reserve) funds the +875 MiB of Q6_K weights.
Projected landing ~2.7 GiB free, inside the 2-3 GiB floor; measure on
boot, step the pool one 12,288-token increment if it lands under 2 GiB.

- payload dir MiMo-Q6K/ made self-contained (mmproj hardlinked from
  MiMo-Q5KM/, link-count-2 verified)
- env/serve/deployer/bats repointed; download script now fetches and
  verifies Q6_K (7,793,710,624 B, ef96d05a...) with Q5_K_M documented as
  the rollback; payload sha verified live on the host before deploy
- seam green 14/14 against the stub engine
