    REST + AG-UI API for integrating your product with Persona's agent

    Every endpoint here is a server-to-server call — see the Integration Guide
    for where in your own stack to call each one from, and how the same endpoint
    serves both Project-level and per-end-user requests via the
    `x-persona-external-user-id` header.
