Summary: HuggingChat adds Model Context Protocol support

Why It Matters: The platform is moving from a static model repository to an interactive chat interface that can connect to external data and tools.

What Changed:

• Replaced the main community hub page with the HuggingChat interface.
• Added support for Model Context Protocol (MCP) to connect AI models to local data.
• Introduced "Omni," a feature that automatically picks the best AI model for a user's question.
• Removed links to enterprise services, datasets, and documentation from the main view.
• Added quick-start prompts for news, travel planning, and gift ideas.
