fix(9router): a sudo update gives root's npm its own cache

Browse Source 
The AgentHub unit makes /root inaccessible (InaccessiblePaths=), so root's
npm failed at mkdir /root/.npm with ENOENT (exit 254). A sudo run now passes
--cache /var/cache/agenthub-9router-npm; the sudoers rule names that argv.

**Update 9router** (`server/lib/nine-router-update.js`; the AI Proxy page's button beside Config 9router, an admin's only — `/ai-proxies/9router` and `/ai-routers/9router` are in `ADMIN_WRITE_PREFIXES`). `GET /api/ai-proxies/9router/update` answers `{ installed, version, latest, updateAvailable, running, managedBy: "systemd"|"process"|null, blocker: {code, message, command?}|null, job }`. `POST` starts one job (202; `EBUSY` while one runs, else 409 with the blocker's code — checked BEFORE anything is stopped) of three steps, each `pending|running|done|failed|skipped`:
1. **shutdown** — a running `9router.service` user unit is `systemctl --user stop`ped; otherwise this account's processes whose argv names the install's `cli.js` get SIGTERM, then they and their descendants SIGKILL after 5 s; the step waits until the port is free. Skipped when nothing ran.
2. **update** — `npm install -g --prefix <the install's own prefix> --prefer-online 9router@latest`; a prefix this account cannot write runs it under `sudo -n`, only when `sudo -n <npm> --version` succeeds (else `ENOPERM` with `command: "sudo npm install -g 9router@latest"`).
2. **update** — `npm install -g --prefix <the install's own prefix> --prefer-online 9router@latest`; a prefix this account cannot write runs it under `sudo -n` with `--cache /var/cache/agenthub-9router-npm` (root's HOME is inaccessible inside the AgentHub unit; the sudoers rule must name that exact argv), only when `sudo -n <npm> --version` succeeds (else `ENOPERM` with `command: "sudo npm install -g 9router@latest"`).
3. **relaunch** — only when 9router was running before: `systemctl --user start 9router.service`, or `node cli.js --tray --no-browser --skip-update -p <old port> [-H <old host>]` detached in its own `systemd-run --user --scope` (plain detached spawn without one); done once the port answers. Runs even after a failed update.
**`POST /api/ai-proxies/test`** answers the question saving cannot: does this endpoint, with this key, actually serve this model — for each CLI? It sends, in parallel and with a 15 s timeout each, one Anthropic-style message capped at a single output token to `<baseUrl>/v1/messages` (what Claude Code calls) and one OpenAI Responses call (`max_output_tokens: 16`) to `<baseUrl>/v1/responses` (what Codex calls). A proxy that answers is a `200` here whatever it replies: `{ claude: { ok, status, message }, codex: { ok, status, message } }`, each carrying the proxy's own words (truncated to 300 characters), `status` `null` when nothing answered at all. A proxy that serves only one wire shape shows one green line and one red. Only bad input is a 4xx.
