CUB-125: implement real-time SSE/WebSocket in React frontend

- Add useSSE hook with exponential back-off reconnect (1s → 30s)
- Add useRealtimeSync hook: maps SSE events to React Query invalidation
  (agent.status → agents; agent.task/agent.progress → tasks+agents; fleet.update → all)
- Add SSEContext/SSEProvider so connection status is available app-wide
- Mount SSEProvider in main.tsx inside QueryClientProvider (no polling)
- Show live/connecting/reconnecting/disconnected badge in sidebar + mobile header
- Update SettingsPage: replace polling interval UI with SSE status panel
- Disable React Query polling (staleTime 60s); all updates pushed via SSE

+# 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.

+## 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
+# 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
-ng serve
+## React Compiler
+
+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:
-
-```bash
-ng generate component component-name
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    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...
+    },
+  },
+])
 ```
-
-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.
