Feature request: Support Agent Discovery Protocol (/.well-known/agent-discovery.json)

[walkojas-boop]

Problem

AI agents have no standard way to discover services at a domain.

Proposal

Support the Agent Discovery Protocol -- domains publish agent services at /.well-known/agent-discovery.json. One fetch, all services discovered.
