ci: staggered deployment pipeline + runner setup guide

Three-track deployment:
- v*.*.*-rc.* → Tanko canary (test first)
- v*.*.* → All Hermes agents (after canary)
- az-v*.*.* → kagentz (Agent Zero track)

Runner setup: docs/RUNNER-SETUP.md — deploy on CT 116 via Docker

+# Gitea Actions Runner Setup
+
+## Prerequisites
+- Gitea admin access (root user or token with admin:actions scope)
+- Docker on the runner host (CT 116 recommended — already has Docker)
+
+## Step 1: Get Runner Registration Token
+```bash
+# On the Gitea host (CT 110) or via Gitea admin API:
+ssh root@192.168.68.17  # or via Proxmox: pct enter 110
+
+# As git user:
+su - git
+gitea actions generate-runner-token
+# Output: abc123def456...
+```
+
+Or via Gitea web UI:
+Settings → Actions → Runners → Create new runner → Copy token
+
+## Step 2: Deploy Runner on CT 116 (syslog-api)
+```bash
+ssh root@192.168.68.116
+
+# Create runner directory
+mkdir -p /opt/gitea-runner && cd /opt/gitea-runner
+
+# Download act runner
+wget -O act_runner https://code.gitea.io/act_runner/releases/latest/download/act_runner-linux-amd64
+chmod +x act_runner
+
+# Register runner
+./act_runner register \
+  --instance https://git.sysloggh.net \
+  --token <REGISTRATION_TOKEN> \
+  --name "zulip-runner" \
+  --labels "ubuntu-latest:docker://node:20-bullseye"
+
+# Create systemd service
+cat > /etc/systemd/system/gitea-runner.service << 'SERVICE'
+[Unit]
+Description=Gitea Actions Runner
+After=docker.service
+
+[Service]
+ExecStart=/opt/gitea-runner/act_runner daemon
+WorkingDirectory=/opt/gitea-runner
+Restart=always
+RestartSec=5
+User=root
+
+[Install]
+WantedBy=multi-user.target
+SERVICE
+
+systemctl daemon-reload
+systemctl enable --now gitea-runner
+```
+
+## Step 3: Verify
+```bash
+journalctl -u gitea-runner -f --no-pager
+# Look for: "runner registered" or "listening for jobs"
+
+# In Gitea UI: Settings → Actions → Runners → should show "zulip-runner" active
+```
+
+## Step 4: Test
+Push a tag to trigger the pipeline:
+```bash
+git tag v1.1.0-rc.1   # Canary → Tanko only
+git push origin v1.1.0-rc.1
+
+# If canary passes:
+git tag v1.1.0          # Production → all Hermes
+git push origin v1.1.0
+
+# For Agent Zero:
+git tag az-v1.0.0       # Agent Zero → kagentz
+git push origin az-v1.0.0
+```
+
+## Tag Convention
+
+| Tag Pattern | Deploys To | Environment |
+|------------|------------|-------------|
+| `v*.*.*-rc.*` | Tanko only | `canary` |
+| `v*.*.*` | All Hermes agents | `production` |
+| `az-v*.*.*` | kagentz only | `agent-zero` |
