Discovery — /.well-known

Publishes machine-readable descriptors so agents can discover which agent-web features the site exposes:

• /.well-known/agent.json — compact capability map (soft-deprecated)
• /.well-known/ai-catalog.json — Agentic Resource Discovery catalog (specVersion 1.0) with CORS Access-Control-Allow-Origin: *
• /.well-known/mcp/server-card.json — MCP Server Card (v1 schema) for the site's WebMCP surface; Streamable HTTP remotes only when the optional remote bridge is enabled

Only enabled domains appear as catalog entries. Optional Web Bot Auth (RFC 9421) remains behind the webbotauth extra and DISCOVERY.WEB_BOT_AUTH.
