Module discovery 

Agent card discovery with HTTP caching.

A2A agents publish their AgentCard at a well-known URL. This module provides helpers to fetch and parse the card.

The default discovery path is /.well-known/agent.json appended to the agent’s base URL.

Per spec §8.3, the client supports HTTP caching via ETag and If-None-Match / If-Modified-Since conditional request headers.
