Update MCP server to use domain-specific endpoints

Changes:
- Updated default endpoints to use https://hive.home.deepblack.cloud
- Added support for HIVE_TIMEOUT environment variable
- Created .env.example with multiple deployment configurations
- Updated Claude Desktop configuration for production/development
- Updated README with comprehensive configuration guide

Production endpoints:
- API: https://hive.home.deepblack.cloud
- WebSocket: wss://hive.home.deepblack.cloud

Development fallback to localhost still available via env vars.

-## Environment Variables
+## Configuration
 
-- **`HIVE_API_URL`** - Hive backend API URL (default: `http://localhost:8087`)
-- **`HIVE_WS_URL`** - Hive WebSocket URL (default: `ws://localhost:8087`)
+The MCP server connects to the Hive backend using domain endpoints by default. You can customize this by setting environment variables:
+
+**Production (Default):**
+- **`HIVE_API_URL`** - `https://hive.home.deepblack.cloud`
+- **`HIVE_WS_URL`** - `wss://hive.home.deepblack.cloud`
+
+**Development/Local Testing:**
+- **`HIVE_API_URL`** - `http://localhost:8087`
+- **`HIVE_WS_URL`** - `ws://localhost:8087`
+
+**Additional Options:**
+- **`HIVE_TIMEOUT`** - Request timeout in milliseconds (default: `30000`)
+
+Copy `.env.example` to `.env` and modify as needed for your deployment.
