frank-large: swap to stock llama.cpp serving Qwen3.8-27B UD-Q8_K_XL with DFlash2

Replace the Kairic Edge ROCmFPX build with the unsloth b11030 stock
llama.cpp prebuilt (ROCm gfx1151) serving unsloth/Qwen3.8-27B-GGUF:
UD-Q8_K_XL (a 27B dense model, 31.5 GiB) with the z-lab DFlash2 Q4_K_M
drafter (depth 4) on the gfx1151 iGPU.

Serving shape: one 262,144-token conversation, q8_0 KV (the build lacks
fp8), text-only, greedy sampling, Qwen-Sharp v22.4.0 template.

- scripts/serve-frank-large.sh: stock llama.cpp + DFlash2 spec decode
- scripts/frank-large.env: new model/drafter/runtime, 262144 ctx / 1 slot
- scripts/download-frank-large.sh: per-file fetch, verify mode, idempotent
- scripts/frank-large.service: updated description
- scripts/deploy-remote.sh: updated pkill pattern + asset gates
- tests/frank_large_unit.bats: new model/runtime/spec assertions
- docs: new runbook (active), Kairic Edge runbook retired (rollback target)
