CUB-200: fix event-loss race — register handlers before readLoop starts

Move registerEventHandlers() call before the readLoop goroutine starts
in connectAndRun(). This eliminates the startup window where live gateway
events were actively read and dropped as 'unhandled' because handler
registration happened only after initialSync completed.

The handlers only depend on c.agents and c.broker, which are wired in the
constructor — they do not require initialSync to have completed.

Also adds TestConnectAndRun_EventNotLostDuringSync regression test that
sends a live presence event during initial sync and asserts it is not lost.

All gateway tests pass with -race.

+# 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
+

+# Control Center
+
+> Real-time agent fleet dashboard for the OpenClaw AI development team.
+
+Control Center monitors and controls the full CubeCraft Creations AI agent fleet — Otto, Rex, Dex, Hex, Pip, Nano, Sketch, Bob, Stuart, Norbert, and Flip. It provides live agent status, task progress, session logs, and a command interface, backed by SignalR for push-based updates directly from the OpenClaw gateway.

+
+## Tech Stack
+
+| Layer | Technology |
+|---|---|
+| Backend | ASP.NET Core Web API (.NET 8) |
+| Database | PostgreSQL (snake_case via EF Core) |
+| ORM | Entity Framework Core |
+| Real-time | SignalR (`AgentStatusHub`) |
+| Frontend | Angular (latest), Angular Material, Angular Signals |
+| API Client | TypeScript package (`api-client/`) |

+## Domain Model
+
+### Agent
+
+| Field | Type | Description |
+|---|---|---|
+| `Id` | `Guid` | Primary key |
+| `Status` | `AgentStatus` | Current agent state |
+| `Task` | `string?` | Active task description |
+| `Progress` | `int?` | Task completion % (0–100) |
+| `SessionKey` | `string` | OpenClaw session identifier |
+| `Channel` | `string` | Source channel (telegram, slack, etc.) |
+| `LastActivity` | `DateTime` | Last event timestamp |
+| `CreatedAt` / `UpdatedAt` | `DateTime` | Audit fields |
+
+### AgentStatus enum
+
+| Value | Integer | Meaning |
+|---|---|---|
+| `Active` | 0 | Agent is executing a task |
+| `Idle` | 1 | Agent is waiting for work |
+| `Thinking` | 2 | Agent is reasoning/planning |
+| `Error` | 3 | Agent hit an unrecoverable state |
+
+---
+
+## Key Design Decisions
+
+1. **Angular Signals** — Reactive state management. No NgRx — kept intentionally simple.
+2. **Adaptive layout** — Sidebar nav (NavRail) on desktop/kiosk (≥768px); bottom nav on mobile.
+3. **Tactical Dark Mode** — Theme via CSS custom properties in `styles.scss`.
+4. **SignalR fleet group** — Clients call `JoinFleet()` to subscribe to all agent updates broadcast by the hub.
+5. **Backend push model** — Hub uses `IHubContext<AgentStatusHub, IAgentStatusClient>` extension methods to push to clients; no polling.
+6. **Gateway bridge** — `GatewayEventBridgeService` connects the OpenClaw gateway WebSocket to the SignalR hub.

+
+## Getting Started
+
+### Prerequisites
+
+- .NET 8 SDK
+- Node.js 20+
+- Docker
+- PostgreSQL
+- Running OpenClaw gateway (for live agent events)
+
+### Backend
+
+```bash
+cd backend
+
+# Restore and build
+dotnet restore
+dotnet build
+
+# Apply migrations
+dotnet ef database update --project ControlCenter
+
+# Run API
+dotnet run --project ControlCenter
+```
+
+API runs at `http://localhost:5000` · Swagger at `http://localhost:5000/swagger`
+
+### Frontend
+
+```bash
+cd frontend
+npm install
+ng serve
+```
+
+Frontend runs at `http://localhost:4200`
+
+---
+
+## Configuration
+
+`backend/ControlCenter/appsettings.json` — override in `appsettings.Development.json` or environment variables:
+
+| Key | Default | Description |
+|---|---|---|
+| `ConnectionStrings:DefaultConnection` | *(set in dev config)* | PostgreSQL connection string |
+| `Gateway:WebSocketUrl` | `ws://localhost:3271/ws` | OpenClaw gateway WebSocket URL |
+| `Gateway:AuthToken` | `""` | Gateway auth token |
+| `Cors:AllowedOrigins` | `localhost:4200`, `localhost:5000` | Frontend origins for CORS |
+
+---
+
+## Real-Time Events
+
+SignalR hub endpoint: `/hubs/agent-status`
+
+### Hub Methods (server → client)
+
+| Method | Payload | Description |
+|---|---|---|
+| `ReceiveStatusUpdate` | `AgentStatusUpdateDto` | Agent status changed |
+| `ReceiveAgentList` | `Agent[]` | Full fleet snapshot on join |
+
+### Client → Server
+
+| Method | Description |
+|---|---|
+| `JoinFleet()` | Subscribe to all agent updates |
+| `LeaveFleet()` | Unsubscribe |
+| `SendStatusUpdate(dto)` | Push a status update (internal use) |
+
+---
+
+## Pages
+
+| Route | Page | Description |
+|---|---|---|
+| `/hub` | Command Hub | Live agent grid — status, task, progress |
+| `/logs` | Logs | Agent session log viewer |
+| `/projects` | Projects | Linear project tracking view |
+| `/sessions` | Sessions | OpenClaw session browser |
+| `/settings` | Settings | App configuration |
+
+---
+
+## Agent Fleet
+
+| Agent | Role |
+|---|---|
+| Otto | Orchestrator — owns the dev lifecycle |
+| Rex | Frontend (Angular) |
+| Dex | Backend (ASP.NET Core) |
+| Hex | Database (schema, migrations) |
+| Pip | Raspberry Pi / Python |
+| Nano | Arduino / ESP32 / ESPHome |
+| Sketch | UX/UI design |
+| Flip | Mobile development |
+| Bob | Content & marketing copy |
+| Stuart | Concept visualization (images) |
+| Norbert | 3D design (OpenSCAD) |
+
+---
+
+## Branch & PR Rules
+
+- All feature branches target `dev` — **never `main`**
+- Branch naming: `agent/<agent>/CUB-N-short-description`
+- PR titles: `CUB-N: short description`
+- PRs require Otto review before Joshua merges
+
+---
+
+## API Overview
+
+| Route prefix | Resource |
+|---|---|
+| `/api/agents` | Agent registry and status |
+| `/api/command` | Issue commands to agents |
+| `/api/logs` | Session log retrieval |
+
+Full schema at `/swagger` when running in dev.

+# 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.
