dankclaw: replace vLLM with CIRU ROCmFPX llama.cpp runtime

Retire the vLLM service (frank-default-small, port 52625) on Dankclaw
and serve jcbtc/Qwen3.8-27B-CIRU-ActiveFPX-PromptForge through the CIRU
ROCmFPX llama.cpp runtime instead.

- Build llama-server from ciru-ai/ROCmFPX tag
  qwen3.8-activefpx-promptforge-v2.3 (commit 103af8b41) against the
  private TheRock ROCm 7.15 SDK in the retired ling3-ciru venv. The
  model card requires ROCm 7.15 for the advertised Strix Halo
  performance; the system ROCm 7.2.4 selects slower kernels.
  CK pinned at fdf4bb7fcc984811cef48ce817d89aac064b984a; generated
  ck/config.h + ck/version.h copied into the CK source tree so the
  ggml-hip build can include them. LLAMA_BUILD_WEBUI=OFF (HF bucket
  llama-ui returns 404; server is consumed via the OpenAI API).
- New scripts/serve-frank-small.sh + frank-default-small.env: 64K ctx,
  one slot, f16 KV, context checkpoints, prompt cache, native depth-4
  MTP on ROCm0, PromptForge DualView sidecars (FFN + GDN), temp 0.7
  top-p 0.95, reasoning off. LD_LIBRARY_PATH puts the 7.15 SDK libs
  before any system ROCm.
- Update the systemd unit description (same service name and port).
- deploy.sh: update the dankclaw target comment.
- Docs: new docs/ciru-activefpx-promptforge.md with the build runbook;
  update docs/index.md and AGENTS.md topology.
- The vLLM venvs (vllm-venv, vllm-vk-venv) were moved to
  /home/dank/.AGENTTRASH/ on the target; the vllm-vulkan plugin and
  docs were removed from the repo in an earlier commit.
