feat(frank-medium): swap MXFP4 -> FP8; add the one-command swap toolchain

Checkpoint: just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq ->
orcarouter/Qwen3.8-27B-Uncensored-FP8 (FP8 E4M3 block-wise, 30.9 GB / 7
shards, its own single-layer MTP head). The quantization-aware entrypoint
serves the plain FP8 path: --quantization fp8, ROCM_AITER_UNIFIED_ATTN, MTP
self-speculation (SPEC_METHOD=mtp, SPEC=8). Measured: MTP mean accept 5.66/8
(66.2% draft acceptance), KV pool auto-sized to 461,540 tokens (1.76x),
battery 85.9 t/s decode / 0.06 s TTFT / 179.7 burst-4 (vs MXFP4 92.4/0.22/
248.9). MXFP4 checkpoint stays on disk as the rollback target.

Streamlining: scripts/hf-manifest.py (generate a <filename> <size> <sha256>
manifest from the live repo tree), scripts/hf-fetch.sh (resumable, byte +
sha256 verified, idempotent fetch), scripts/swap-frank-medium.sh (generate
manifest -> download -> detect quantization -> edit the quadlet -> deploy).

Docs: new frank-medium-model-swap runbook; radiance runbook, both indexes,
AGENTS.md, and log.md flipped to the FP8 shape.
