frank-default-large: add MTP draft head (EasiiX Q8_0, draft-mtp+ngram-mod)
Add speculative decoding via EasiiX/Qwen3.8-Flash-Next-MTP-Strix-Halo-GGUF
Q8_0 sidecar (4.1 GB, qwen4exp architecture matching the main model).
- serve-frank-large.sh: SPEC_ARGS array, draft model existence check,
spec defaults (n_max 4, p_min 0.75, ngl 999, ROCm0)
- frank-default-large.env: MTP tunables section, fix 'no MTP' comment
- kingjones-strix-rocmfp4.md: MTP Draft Head section, spec flags in
serving profile, EasiiX + PR #27739 citations
Set SPEC_TYPE=none in the env to disable speculative decoding.
