Get Agent Well Known Card

Agent-specific well-known discovery endpoint.

Returns the agent card for this specific agent, at /v1/agents/{agent_id}/.well-known/agent-card.json

This allows each agent to have its own well-known endpoint, which is A2A compliant. Later, this can be proxied to subdomains:

• agent1.domain.com/.well-known/agent-card.json -> /v1/agents/{id}/.well-known/agent-card.json
