llm: retire the trio service names — fleet services renamed to frank-archon/frank-dragoon/frank-zealot

The 2026-10-09 wire aliases become the service names everywhere:
systemd units, serve scripts, env files and FRANK_* variables,
deploy-plan/deploy-remote service keys, container names, Prometheus
job names + alert rules, Grafana dashboard queries, bats seams,
runbook filenames, homepage/AGENTS lore, and historical prose.
Rollback tags renamed in lockstep. Residue in the tree: zero.
Retired frank-medium/small/npu names are history and stay.

Known casualty: scripts/patches/*.patch context lines were rewritten;
those retired-era vLLM-fork patches no longer apply byte-exact.

+# Integrity: the file is checked against its declared byte count and sha256
+# (the LFS oid from the Hub tree API, 2026-10-01). NO AUTH HEADER IS USED:
+# the repo is public and ungated (gated: false), and a token on the curl
+# command line is world-readable via /proc/<pid>/cmdline. If this ever needs
+# a token, put it in a mode-600 file and pass it with `curl -K`.
+#
+# Layout after a successful run (MODEL_DIR):
+#   Qwen3.8-27B-UD-Q4_K_XL.gguf   17559178144  (16.35 GiB)
+#
+# WHY Q4 AND NOT THE Q8 SWIFT PAYLOAD: this is the vanilla (non-abliterated)
+# Qwen3.8-27B at UD-Q4_K_XL, ~13 GiB smaller than the Swift UD-Q8_K_XL. Every
+# GiB of weights saved is a GiB of f16 KV the endpoint can hold instead: the
+# KV costs 64 KiB/token (16 full-attention layers x 4 KV heads x 256 head_dim
+# x 2 (K,V) x 2 B), so 4 sessions x 163840 ctx = 640,000 tokens = 39.06 GiB.
+#
+# The speculative drafter is UNCHANGED and still fetched by its own script
+# (scripts/download-frank-dragoon.sh, z-lab's Hub repo). That name must not
+# appear here at all — the frank-dragoon seam greps THIS file for it to prove
+# the drafter was not folded into the payload fetch.
+#
+# NOTE ON MTP: this payload has no baked-in MTP head (the Hub repo ships one
+# separately as MTP/mtp-Qwen3.8-27B-Q4_0.gguf). frank-dragoon does not need it —
+# spec decode here is the block-diffusion drafter, not MTP.
