v0.22.0:0 - configurable vllm port; gitea-release tooling; coexistence roadmap

- Configure Sparks gains a vLLM port field (blank => 8888, our launch-cluster.sh
  default); VLLM_PORT plumbed configureSparks -> sparkConfig.yaml -> main.ts env
  -> config.py. So an adopter whose vLLM listens elsewhere (e.g. 8000) can fix
  the "vLLM unreachable" health check without rebuilding the package.
- Harden numeric env parsing (config._env_int): a blank or malformed port now
  falls back to its default instead of crashing daemon startup (closes a P3
  tech-debt item; the Configure panel passes unset optional fields as "").
- Add scripts/gitea-release.sh + `make release` to publish the built s9pk to
  Gitea Releases, so the OpenClaw adopter pulls updates with a read-only token
  instead of being hand-sent the package.
- Capture the OpenClaw/Johnny-5 coexistence epic and the "control plane, not a
  job runner" stance in ROADMAP.md and Current state.

 - **Known limits:** `/health` blips while the GPU is busy (mitigated client-side); dual-channel can miss a quiet local word under loud remote bleed; connectivity log misses sub-5s outages between 5s polls; diarizer caps at 4 speakers; matrix-bridge badge won't visibly flip on a fast `docker restart` (status re-checked only after the command returns).
 - **Infra gotcha (safety):** passwordless sudo is NOT configured on spark2 — design unprivileged probes for any Spark feature (the badge uses `ip`, not `sudo wg show`). spark2 sits on the `starttunnel` WireGuard subnet (`10.59.211.6/24`, survives reboot). Owner declined SSH-key rotation after the 2026-06-12 history scrub (only the key *name* leaked) — don't re-flag.
 - **Hosting:** self-hosted Gitea — remote `gitea`, branch `master`, over SSH; push after committing. (Wart: commit `8d839e3` is mislabeled `v0.13.0:4` but contains through v0.18.0:0.)
-- **Next:** (1) audio concurrency sweep — only if the Signal Engine dev wants the measured knee; needs owner OK in a quiet window. (2) Otherwise pull from `ROADMAP.md`: local-path/fine-tuned model support (new) or P2 tech-debt. (matrix-bridge Phase 3 shipped v0.21.0:1; only open item is the optional Docker `HEALTHCHECK` if the bot dev asks. Parakeet long-audio guard deferred — rationale in ROADMAP.)
+- **Next — committed 2026-06-17: OpenClaw/Johnny-5 coexistence epic (full plan + design stance in `ROADMAP.md` → "Cluster coordination").** Stance: Spark Control = control plane / GPU arbiter, **not** a job runner; business cron jobs live in separate services that *call* its swap API (swaps are already API-driven via `POST /api/swap`). Sequence: (1) **configurable `VLLM_PORT`** — DONE in tree, staged as **v0.22.0:0** (Configure-Sparks field, blank ⇒ 8888; + `_env_int` hardening in `config.py` so a blank/bad port no longer crashes startup, killing a P3 tech-debt item). **Not yet built/installed/committed — awaiting go/no-go.** (2) local-path/fine-tuned models (in ROADMAP under Dashboard). (3) configurable topology (service→Spark→port map + container names). (4) coordination layer (swap lock + swap webhook + schedule visibility) — only when our own automation lands. Still-open older threads: audio concurrency sweep (only if the Signal Engine dev wants the knee; needs a quiet window); optional matrix-bridge Docker `HEALTHCHECK` if the bot dev asks; Parakeet long-audio guard deferred (rationale in ROADMAP).
