Add Integrations and Deployment stub pages to docs sidebar

Add Integrations group (GitHub, Daytona, Slack, exe.dev, Brave Search)
to Documentation tab above Reference. Replace generic Deployment page
with platform-specific stubs (Railway, Render, Fly.io, Digital Ocean)
in the Guides tab.

-## Binding and TLS
-
-By default, `arc serve` binds to `127.0.0.1:3000` (localhost only). For production, either:
-
-1. **Reverse proxy** — Keep the default binding and place nginx, Caddy, or an ALB in front:
-
-```nginx
-upstream arc {
-    server 127.0.0.1:3000;
-}
-
-server {
-    listen 443 ssl;
-    server_name arc.example.com;
-
-    ssl_certificate /etc/tls/cert.pem;
-    ssl_certificate_key /etc/tls/key.pem;
-
-    location / {
-        proxy_pass http://arc;
-        proxy_http_version 1.1;
-
-        # Required for SSE event streams
-        proxy_set_header Connection '';
-        proxy_buffering off;
-        proxy_cache off;
-    }
-}
-```
-
-2. **Direct TLS** — Configure TLS in `server.toml`:
-
-```toml
-[api.tls]
-cert = "/etc/arc/tls/cert.pem"
-key = "/etc/arc/tls/key.pem"
-ca = "/etc/arc/tls/ca.pem"
-```
-
-<Note>
-If you use a reverse proxy, set `api.base_url` in `server.toml` to the external URL so that API responses include correct links.
-</Note>
-
-## Running as a service
-
-Example systemd unit:
-
-```ini
-[Unit]
-Description=Arc API Server
-After=network.target
-
-[Service]
-Type=simple
-User=arc
-WorkingDirectory=/opt/arc
-EnvironmentFile=/opt/arc/.env
-ExecStart=/opt/arc/bin/arc serve --host 0.0.0.0 --port 3000 --config /etc/arc/server.toml
-Restart=on-failure
-RestartSec=5
-
-[Install]
-WantedBy=multi-user.target
-```
-
-## Health checks
-
-The API server exposes a health endpoint at `GET /health` that returns `{"status": "ok"}`. No authentication is required. Use this for load balancer health checks, container orchestration probes, or uptime monitoring.
-
-```bash
-curl http://localhost:3000/health
-```
-
-## Concurrency tuning
-
-| Setting | Default | Where |
-|---|---|---|
-| Max concurrent runs | 5 | `--max-concurrent-runs` or `max_concurrent_runs` in `server.toml` |
-| Max parallel branches per node | 4 | `max_parallel` attribute on parallel nodes in DOT |
-| Subagent depth | 1 | Hardcoded (subagents can spawn one level deep) |
-| Max tool rounds per turn | 200 | Hardcoded |
-| Default retries | 3 | `default_max_retry` graph attribute (or `max_retries` per node) |
-
-## Stall watchdog
-
-Arc cancels a run if no handler events are emitted for a configurable duration. This protects against hung agents or unresponsive LLM providers.
-
-| Setting | Default | Where |
-|---|---|---|
-| `stall_timeout` | `600s` (10 min) | Graph attribute: `graph [stall_timeout="300s"]` |
-
-Set to `0s` to disable: `graph [stall_timeout="0s"]`.
-
-## Log files
-
-Arc writes two kinds of logs:
-
-- **Application logs** — `~/.arc/logs/YYYY-MM-DD.log` (structured, controlled by `ARC_LOG`)
-- **Run logs** — `~/.arc/logs/{run_id}/progress.jsonl` (one event per line)
-
-The logs directory is not currently configurable and has no automatic retention. For production, set up external log rotation (e.g. `logrotate`) or periodic cleanup of old run directories.
-
-See [Observability](/execution/observability) for the full event schema and analysis tools.
