docs: qwen3.6-moe unreachable incident (2026-08-16) + topology reconciliation

- FastFlowLM doc: incident section (EXEC-203 exec-bit loop, client model
  ID 'frank-default-small' rejected, swap churn 14:48-15:03), FLM
  unknown-tag fallback behavior (silently loads llama3.2:1b default),
  working models.json entry recorded, promotion status -> qwen3.6-moe
- AGENTS.md: Overview + target map now reflect qwen3.6-moe:35b-a3b on
  the NPU endpoint (Dankserver llama.cpp 35B service stopped)
- deployment.md: topology table current; Dankserver frank-default-small
  section marked STOPPED 2026-08-16 (alias moved to the NPU endpoint)

+> Note (2026-08-16): the `frank-default-small` alias now belongs to the FastFlowLM NPU endpoint on Dankclaw (port 52625, see [[FastFlowLM NPU Inference]]). The llama.cpp Qwen3.6-35B-A3B service on Dankserver described below is stopped (verified `inactive` 2026-08-16). The text below is kept as history.
 
 The active service on Dankserver runs llama.cpp (upstream, `b10108+`) and serves the HauhauCS Qwen3.6-35B-A3B uncensored `Q6_K_P` model under the alias `frank-default-small` on port 7770. It uses **ngram-mod** speculative decoding (`--spec-ngram-mod-n-min 48 / n_max 64 / n_match 24`), **4 parallel slots** at 175104 context each (pool 700416), and mmproj vision. **36 of 40 MoE expert layers** stay on CPU (`--n-cpu-moe 36`); 4 expert layers' weights are back on GPU alongside all non-expert tensors (`--gpu-layers all`). KV stays on GPU (K=`f16`, V=`f16`), refitted from 800000 on 2026-08-14 when the pool went dual-f16 (the f16/f16 pool costs 13680 MiB at 700416 cells and did not fit at 800768 cells). Batch 8192 / ubatch 3072, `--ctx-checkpoints 4`, `--no-mmap`. The unit file is `scripts/frank-default-small.service`, symlinked to `/etc/systemd/system/`. It launches through `scripts/serve-llama-frank-small.sh`, which reads tunables from `scripts/frank-default-small.env`.
