/**
 * Host computer-use proxy SSE events (`host_cu_request` / `host_cu_cancel`).
 *
 * Server → client instructions that proxy computer-use actions (click,
 * type, screenshot, …) to the desktop client when running as a managed
 * assistant. The client executes and POSTs the result back to
 * `/v1/host-cu-result`; `host_cu_cancel` withdraws an in-flight request.
 *
 * Canonical wire-contract source. Daemon code imports the types
 * directly from this file; external consumers import via
 * `@vellumai/assistant-api`.
