Chat SDK renderer for json-render that turns JSON specs into native chat cards (Block Kit on Slack, Adaptive Cards on Teams, and the card format of other Chat SDK adapters). Use when working with @json-render/chat, building bots that post rich messages with tables, charts, fields, or buttons, streaming a generated card into a chat thread, or when the user mentions Chat SDK, Slack Block Kit, or Teams Adaptive Cards together with json-render.
