/**
 * Streamable Invoke Protocol v1 — Zod schemas.
 *
 * Single source of truth for the client→agent invoke turn. Mirrors Anthropic's
 * Messages streaming format exactly (message_start / content_block_{start,delta,stop}
 * / message_delta / message_stop / ping / error). UI rendering is expressed as
 * plain `tool_use` blocks calling the `ggui_render` / `ggui_render_blueprint`
 * client tools — no ggui-specific block type.
 *
 * TS types in types/invoke.ts are derived from these via z.infer. Consumers
 * (@ggui-ai/server, @ggui-ai/mcp-apps-react) import schemas for runtime validation
 * and types for authoring.
