Publish an MCP Server Card for agent discovery (SEP-1649)

[jazzsequence]

Problem

MCP Server Card not found at /.well-known/mcp/server-card.json. AI agents cannot discover MCP capabilities.

Goal

Enable MCP-compatible agents to discover the site's MCP server and its capabilities.

Fix

Serve an MCP Server Card at /.well-known/mcp/server-card.json containing:

• serverInfo — name and version
• transport — endpoint URL
• capabilities — supported MCP capabilities

The schema is being standardized; track progress at the linked PR.
