docs(frank-tts): what makes a locally built voice image stale, and what the warm text must survive

Three pages, all from faults found this session:

- `LLM/deployment.md` gains "Locally built images": which images have no
  registry digest, what the `cfhash` skip is for, why it must cover every COPY'd
  file (the silent shape: build skipped, /health green, old code serving), and
  the base-image half of the law — the engine's `useradd`, because the pinned
  ubuntu:24.04 has no `adduser`.
- `Dankclaw/Frank TTS Engine.md` troubleshooting gains the two lines an operator
  actually needs: every voice cold on a fresh boot with a hand-run hook
  succeeding (= `WARM_TEXT` arrived quoted, `podman exec … env | grep WARM_TEXT`
  proves it), and a 502 from the façade beside a 200 `/health` from the engine
  (model loaded ≠ voices registered). The stale-warmer row is re-keyed to the
  new rebuild rule.
- `Dankclaw/Voice Packs.md` step 4 was wrong: it told the next agent to restart
  the engine *instead of* the warm hook because the hook "only registers packs it
  has not seen". It registers every pack on every run and the engine replaces a
  name it already holds — `tools/tts-server.cpp:148` at the pinned commit:
  "Re-registering a name replaces the previous entry." A restart is what an
  engine bump needs (the registry is memory-only), never worse, only slower.
- `Dankclaw/Frank TTS.md` deploy command re-keyed to `./scripts/deploy.sh
  dankclaw --service frank-tts`, the way it is actually deployed; the raw
  `deploy-remote.sh` form is plumbing.

+`./scripts/deploy.sh dankclaw --service frank-tts` (or `--service frank-tts-engine --service frank-tts` for the pair):
 builds the façade image, installs **both** Quadlet units — including the
 engine's `.network` file, because a referenced `Network=` file the generator
 cannot find means the façade unit is not produced at all — creates
