/**
 * Collision-free request-id generation for request/response correlation.
 *
 * AppServerClient's built-in nextRequestId() is a bare per-instance counter
 * that restarts at 1, so two client instances (for example two session
 * objects, or a session plus a management request) each emit ids like
 * `conversation_retrieve-1`. When more than one connection is involved the
 * app-server can deliver request-correlated responses where both ids look
 * identical, and the wrong caller's pending request resolves (or times out).
 *
 * Ids generated here embed a per-client random nonce plus a process-wide
 * monotonic counter, so no two clients in the same process can ever emit the
 * same id, and cross-process collisions are vanishingly unlikely.
