/**
 * FunCaptcha (Arkose Labs) solver — API-level approach.
 *
 * Ported and integrated from:
 *   - noahcoolboy/funcaptcha  (BDA fingerprint generation, session/challenge API, crypto, api-breakers)
 *   - useragents/Funcaptcha-Audio-Solver  (audio challenge flow + speech-to-text)
 *
 * This module does NOT require a browser. It speaks directly to the Arkose
 * Labs API: generate BDA → get token → get challenge → solve (audio or
 * vision). The solved token is then injected back into the page.
 *
 * When audio mode is unavailable or denied, falls back to vision-based
 * solving through the existing visionClassify pipeline.
