/**
 * Settings-aware stream wrapper shared by the main agent (sdk.ts) and the

 *
 * verbosity, stream watchdog budgets, per-provider in-flight caps, and the loop
 * guard out of `Settings`
 * per request, layering them onto whatever options the caller passed. Before
 * this helper existed, advisor turns called bare `streamSimple` while the main
 * turn went through an inline closure that read these settings — so an advisor on
 * OpenRouter never saw `providers.openrouterVariant`, breaking sticky routing
 * and OpenRouter response-cache hits across advisor calls.
