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.
