frank-primary cutover: tcclaviger RDNA4 stack, 600k ctx / 3 sessions / q8-q8 KV

Replace the R9V radiance fork with the tcclaviger RDNA4 vLLM stack (the
digest-pinned image the 2026-09-29 tuning campaign measured), serving
orcarouter/Qwen3.8-Flash-Next-Uncensored-FP8 (131 shards, 172.8 GiB,
already on disk) with MTP4 spec decode.

Qualified by boot probe on 2026-09-29:
- MAXLEN=200000 x SEQS=3 (600k total) at --kv-cache-dtype fp8 (q8/q8 KV):
  'GPU KV cache size: 729,545 tokens; Maximum concurrency for 200,000
  tokens per request: 3.65x' at KV_BYTES 7.2 GiB PER RANK.
- KV_BYTES is per-rank: global 16G and 9G both OOM (worker tried to
  allocate the full size; ~7.5 GiB/rank is the ceiling with the arena).
- prefetch OFF by law (telemetry: 36% precision, ~50% wasted traffic);
  TunableOp off (corrupts numerics).
- decode at this shape: 42.94/34.55/36.09 tok/s; arena 6,032 slots.

Trio: frank-primary.env (all FRANK_PRIMARY_* keys), serve-frank-primary.sh
(direct podman run; entrypoint execs vllm serve; waits on the container),
frank-primary.service (root unit, same ExecStop law, new container name
frank-primary-qwen). Deployer gates rewritten (image digest + shard count
+ weight-map index). download-frank-primary.sh is now inventory/verify
(repo is GATED — 401 anonymous, masked LFS hashes; payload already on
disk). Seam rewritten for the new contract. Pre-cutover tag:
frank-primary-r9v-q8-20260929.

# Replaces the llama.cpp frank-primary unit (same port, same served alias;
# harness models.yml unchanged in id, retuned for the 131072 window). The
# serve script drives the R9V fork's own launcher through the docker->podman
# shim and then waits on the container, so a crashed engine is a nonzero
# ExecStart and Restart=on-failure is real.
# Same port, same served alias; the harness models.yml id is unchanged.
# The serve script drives `podman run` directly (the image entrypoint execs
# `vllm serve`) and then waits on the container, so a crashed engine is a
# nonzero ExecStart and Restart=on-failure is real.
#
# WHY A ROOT UNIT (not a rootless quadlet): the tiered-expert shape pins tens
# of GiB of host RAM (the UVA expert host copy plus the 16 GiB PLE pinned
# reserve). Pinned pages are charged against RLIMIT_MEMLOCK; dank's login
# session on this host carries 8 MiB and a user quadlet is capped by the user
# manager's own hard limit — raising that means restarting user@1000.service
# and bouncing every user container on the host. A root unit grants
# LimitMEMLOCK=infinity to the dank process via PID1, and the image stays in
# dank's rootless podman storage (the shim drives podman as dank).
