CUB-CI: Consolidate CI — switch to ubuntu-latest with manual Go/Node install

- Remove custom go-react runner label (was inconsistent on PR branches)
- Replace with ubuntu-latest + manual Go 1.23 / Node 22 install
  (actions/setup-go and setup-node don't work with Gitea Act runner)
- Remove duplicate build-dev.yaml workflow (already deleted)
- All steps: Go test → Go build → npm ci → npm lint → npm build
- Docker push on push events only (unchanged)

+# Control Center Deployment Guide
+
+This document covers the Docker Compose deployment and kiosk configuration for the Control Center Go + React application.
+
+## Quick Start
+
+```bash
+# Start all services (backend, frontend, database)
+docker compose up -d
+
+# View logs
+docker compose logs -f
+
+# Stop all services
+docker compose down
+
+# Stop and remove volumes (database data)
+docker compose down -v
+```
+
+## Architecture
+
+```
+┌─────────────────┐
+│   Frontend      │  Port 3000 (host) → 80 (container)
+│   React + nginx │  Serves SPA, proxies /api/ to backend
+└────────┬────────┘
+         │
+         │ HTTP
+         │
+┌────────▼────────┐
+│   Backend       │  Port 8080 (host) → 8080 (container)
+│   Go HTTP API   │  PostgreSQL-backed REST API
+└────────┬────────┘
+         │
+         │ PostgreSQL
+         │
+┌────────▼────────┐
+│   PostgreSQL    │  Port 5432 (internal only)
+│   Database      │  Persistent volume at /var/lib/postgresql/data
+└─────────────────┘
+```
+
+## Services
+
+### Backend (`go-backend`)
+
+- **Image**: Custom `alpine:latest` with Go binary
+- **Port**: 8080
+- **Build**: Multi-stage from `go-backend/Dockerfile`
+- **Environment Variables**:
+  - `PORT` (default: 8080)
+  - `DATABASE_URL` (PostgreSQL DSN)
+  - `CORS_ORIGIN` (default: `*`)
+  - `LOG_LEVEL` (default: `info`)
+  - `ENVIRONMENT` (default: `development`)
+  - `GATEWAY_URL` (OpenClaw gateway endpoint)
+
+### Frontend (`frontend`)
+
+- **Image**: `nginx:1.27-alpine`
+- **Port**: 80 (internal) → 3000 (host)
+- **Build**: Multi-stage from `frontend/Dockerfile`
+  - Node 22 for build
+  - Nginx 1.27 for serving
+- **Config**: Custom nginx config in `frontend/nginx.conf`
+- **Environment Variables**:
+  - `VITE_API_URL` (passed at build time via Vite config)
+
+### Database (`db`)
+
+- **Image**: `postgres:16-alpine`
+- **Port**: 5432 (internal only)
+- **Volume**: `postgres-data:/var/lib/postgresql/data`
+- **Environment Variables**:
+  - `POSTGRES_USER` (default: `controlcenter`)
+  - `POSTGRES_PASSWORD` (default: `controlcenter`)
+  - `POSTGRES_DB` (default: `controlcenter`)
+
+## Kiosk Mode
+
+For dedicated display installations (e.g., control center dashboard), Chromium can run in kiosk mode.
+
+### Installation
+
+1. **Install the systemd service** (on Debian/Ubuntu with systemd):
+
+```bash
+sudo cp kiosk/control-center-kiosk.service /etc/systemd/system/
+sudo systemctl daemon-reload
+```
+
+2. **Enable auto-start**:
+
+```bash
+sudo systemctl enable control-center-kiosk
+```
+
+3. **Start the service**:
+
+```bash
+sudo systemctl start control-center-kiosk
+```
+
+4. **Check status and logs**:
+
+```bash
+sudo systemctl status control-center-kiosk
+sudo journalctl -u control-center-kiosk -f
+```
+
+### Manual Launch
+
+```bash
+# From project root
+./kiosk/start-kiosk.sh http://localhost:3000
+```
+
+### Uninstall
+
+```bash
+# Stop and disable service
+sudo systemctl stop control-center-kiosk
+sudo systemctl disable control-center-kiosk
+sudo rm /etc/systemd/system/control-center-kiosk.service
+sudo systemctl daemon-reload
+```
+
+### Kiosk Requirements
+
+- **Browser**: `chromium-browser` (install via `apt-get install chromium`)
+- **Display**: X11 session with `DISPLAY=:0`
+- **User**: Must run as a user with X11 access (typically `overseer`)
+- **Permissions**: Read access to the project directory
+
+## Environment Variables Reference
+
+### Backend (`go-backend/.env`)
+
+```bash
+PORT=8080
+DATABASE_URL=postgresql://controlcenter:controlcenter@localhost:5432/controlcenter?sslmode=disable
+CORS_ORIGIN=*
+LOG_LEVEL=info
+ENVIRONMENT=development
+GATEWAY_URL=http://localhost:18789/api/agents
+GATEWAY_POLL_INTERVAL=5s
+```
+
+### Frontend (build-time)
+
+```bash
+VITE_API_URL=http://localhost:8080
+```
+
+### Docker Compose
+
+Set via `services.<name>.environment` in `docker-compose.yml`:
+
+```yaml
+services:
+  backend:
+    environment:
+      - DATABASE_URL=...
+  frontend:
+    environment:
+      - VITE_API_URL=...
+  db:
+    environment:
+      - POSTGRES_USER=...
+      - POSTGRES_PASSWORD=...
+      - POSTGRES_DB=...
+```
+
+## Development
+
+### Local Development (non-Docker)
+
+```bash
+# Backend
+cd go-backend
+go run ./cmd/server/main.go
+
+# Frontend
+cd frontend
+npm install
+npm run dev
+```
+
+### Database Migrations
+
+```bash
+# If using pgx/migrate or similar
+# The database is created automatically on first connection if it doesn't exist
+```
+
+## Troubleshooting
+
+### Backend won't connect to database
+
+```bash
+# Check database container status
+docker compose ps
+
+# View database logs
+docker compose logs db
+
+# Test database connectivity from backend
+docker compose exec backend ping db
+```
+
+### Frontend can't reach backend
+
+```bash
+# Check network connectivity
+docker compose exec frontend ping backend
+
+# Verify backend is running
+docker compose logs backend
+```
+
+### Kiosk browser won't start
+
+```bash
+# Check Chromium installation
+which chromium-browser
+
+# Check X11 forwarding
+echo $DISPLAY
+
+# Manual launch for debugging
+./kiosk/start-kiosk.sh http://localhost:3000
+```
+
+### Port conflicts
+
+If ports 8080, 3000, or 5432 are already in use, modify `docker-compose.yml`:
+
+```yaml
+services:
+  backend:
+    ports:
+      - "8081:8080"  # Change host port
+  frontend:
+    ports:
+      - "3001:80"    # Change host port
+```
+
+## Production Considerations
+
+1. **HTTPS**: Add a reverse proxy (nginx/Traefik) for SSL termination
+2. **Database security**: Use strong passwords, enable SSL
+3. **CORS**: Restrict `CORS_ORIGIN` to production domain
+4. **Logs**: Configure log aggregation (e.g., ELK, Loki)
+5. **Backups**: Regular PostgreSQL volume backups
+6. **Monitoring**: Add health checks and alerting
+

+# Frontend
+
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 21.2.8.
+
+## Development server
+
+To start a local development server, run:
+
+```bash
+ng serve
+```
+
+Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
+
+## Code scaffolding
+
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+
+```bash
+ng generate component component-name
+```
+
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
+
+```bash
+ng generate --help
+```
+
+## Building
+
+To build the project run:
+
+```bash
+ng build
+```
+
+This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
+
+## Running unit tests
+
+To execute unit tests with the [Vitest](https://vitest.dev/) test runner, use the following command:
+
+```bash
+ng test
+```
+
+## Running end-to-end tests
+
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
+
+## Additional Resources
+
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

-# Frontend
+# React + TypeScript + Vite
 
-This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 21.2.8.
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
 
-## Development server
+Currently, two official plugins are available:
 
-To start a local development server, run:
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
 
-```bash
+## React Compiler
-ng serve
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
 ```
 
-Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
 
-## Code scaffolding
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
 
-Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+export default defineConfig([
-
+  globalIgnores(['dist']),
-```bash
+  {
-ng generate component component-name
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
