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