Pull request overview

This PR adds support for running application widgets in different contexts within a single process by introducing a client/server architecture for container namespace management. The changes enable the runtime to launch HTML-based applications in external containers while maintaining JavaScript applications in the main process, allowing for better resource isolation and multi-context support.

Key Changes:

• Introduced IExternalApplicationHandler interface and container namespace utilities for managing applications across different execution contexts
• Enhanced JSRuntimeServer to route HTML applications to external handlers while keeping JavaScript apps in the main renderer
• Changed WebSocket server port from 9112 to 5000
