/**
 * Browser-TLS-impersonating HTTP client for grok.com.
 *
 * Thin re-export over the shared `tlsClientBase.ts` factory
 * (`createTlsClientModule`). All provider-agnostic logic (sidecar lifecycle,
 * streaming tail-file, proxy resolution, error classes, Cloudflare challenge
 * detection) lives in the base module; this file supplies only Grok-specific
 * config and preserves the original public export surface.
