feat: auto-deploy tagged releases to CT 126 via signed webhook (0.3.1)

CI's new deploy job (tags only) sends the house HMAC webhook to CT 126; the listener runs /usr/lib/devdesk/devdesk-deploy, which waits for the version in the apt registry and upgrades devdesk with --force-confold. Running sessions are untouched. Hook setup is documented in docs/DEPLOY.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

 CI (`.gitea/workflows/build-deb.yml`):

- A `v*` tag also publishes to `https://code.lotusguild.org/api/packages/LotusGuild/debian` and creates a release.
+- A `v*` tag also publishes to `https://code.lotusguild.org/api/packages/LotusGuild/debian`, creates a release, and auto-deploys to CT 126. A signed webhook runs `devdesk-deploy`, which upgrades the package; see [docs/DEPLOY.md](docs/DEPLOY.md).

 ## Roadmap
- **v1.1:** `devdesk-api` sidecar for the Repo/CI panel, Matrix notifications when you're away, and auto-deploy.
+- **Next:** Matrix notifications when you're away (needs the Ci-Alert hookshot URL).
 - **v2:** Ops Alerts (Grafana) with "Ask Claude" prompts, and file drop.

-## 5. Optional hardening
+## 5. Auto-deploy on release
+A `v*` tag makes CI publish the package, then send a signed webhook (the house HMAC pattern) to CT 126's existing `webhook` listener on :9000. The listener runs `/usr/lib/devdesk/devdesk-deploy <ref>`, which waits for that version in the apt registry and upgrades only `devdesk` with `--force-confold`. Running Claude sessions are untouched. The log is `/var/log/devdesk-deploy.log`.
+
+**Setup, done once:**
+1. Generate a secret.
+2. Add this hook to `/etc/webhook/hooks.json`, next to `126-config-deploy`. The file is local and untracked because it holds secrets.
+   ```json
+   {
+     "id": "devdesk-deploy",
+     "execute-command": "/usr/lib/devdesk/devdesk-deploy",
+     "command-working-directory": "/",
+     "pass-arguments-to-command": [{"source": "payload", "name": "ref"}],
+     "trigger-rule": {"and": [
+       {"match": {"type": "payload-hash-sha256", "secret": "<WEBHOOK_SECRET>",
+                  "parameter": {"source": "header", "name": "X-Gitea-Signature"}}},
+       {"match": {"type": "regex", "regex": "^refs/tags/v[0-9]+\\.[0-9]+\\.[0-9]+$",
+                  "parameter": {"source": "payload", "name": "ref"}}}
+     ]}
+   }
+   ```
+3. Run `systemctl restart webhook`.
+4. Store the same secret as the devdesk repo's Actions secret `WEBHOOK_SECRET`.
+
+## 6. Optional hardening
 Enable the Proxmox firewall on CT 126 (`firewall=1` on net0) and allow tcp/7681 only from 10.10.10.27. The same rule suits code-server on :8680.
