Summary: HuggingChat adds Model Context Protocol support

Why It Matters: The platform is moving from a simple model repository to a functional chat interface that can connect to external data and tools. This makes open-source models more useful for daily tasks.

What Changed:

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