Agent onboarding: build an Add to Agent setup hub

[sajeetharan]

Problem

Developers and agents have no dedicated, user-friendly portal to learn how to integrate and connect DevGlobe's MCP tools to their environments.

Acceptance Criteria

• Build a dedicated, accessible, and responsive /agents page.
• Visual configurations and setup copy controls for VS Code, Claude Desktop, Cursor, and generic Streamable HTTP.
• Include clear links to the endpoint, server card, Agent Skill, and auth docs.

Dependencies

• None.
