// Regression guards for the two device-code providers that returned "ошибка сервера OmniRoute":
//
//   qwen        — QWEN_CONFIG pointed at the bare host qwen.ai, whose device/token paths 404.
//                 The working qwen-code device flow lives at chat.qwen.ai (verified live: 200 +
//                 a valid device_code). Guard: the config uses chat.qwen.ai, never bare qwen.ai.
//   codebuddy-cn— the Tencent state endpoint reads `platform` from the QUERY string, not the JSON
//                 body; body-only returned 400 "platform is empty" (verified live). The fix passes
//                 it as a query param. Guard: requestDeviceCode builds the URL with ?platform=.
//
// Source-level: the real validation is the live upstream 200 (can't be hit from CI); these pin
// the exact change so a revert to the broken host / body-only platform fails here.
