v0.2.0

Merchant and buyer agents, built from this tag by the workflow that published it.

Two binaries per platform, market and user, each a single static file
that needs nothing installed alongside it. They read their configuration from
the environment, and .env.example lists every variable.
The merchant will not start without Upstash Redis, which is deliberate: the
session store is where a negotiation's state lives. The buyer needs the
merchant's two endpoints, USER_MARKET_MCP_ENDPOINT and
USER_MARKET_A2A_ENDPOINT.

dashboard exposed.
