frank-primary: qwen cutover docs + deployer identity + seam re-pin

- AGENTS.md: fleet table + frank-primary section back to qwen FP8 + MTP4
  (37.4-40.6 tok/s, 54% acceptance); GLM runbook moved to the retired index.
- runbook: RETIRED verdict — DFlash2 drafter served and drafted but
  acceptance pinned 1.00-1.38 on every text class including verbatim
  repetition (mis-wired aux capture, not a weak drafter); 5x slower than
  baseline at ~1.2 acceptance.
- log.md: 2026-10-01 rollback entry.
- deploy-remote.sh: LLM_PRIMARY_CONTAINER back to frank-primary-qwen;
  glm-probe joins the legacy sweep list.
- frank_primary_unit.bats: re-pinned to the qwen shape — KV qualification
  law (7.2 GiB/rank, 3.65x concurrency; 9/16 GiB OOM), fp8 q8/q8 KV
  PRESENT, MTP4 PRESENT (3.1-3.4x over the 12.11 no-spec baseline), no tool
  dialect, automatic offload. The old 'MTP buys zero' law carried the
  prefetch tax and is retired.
