* Telegram API proxy preload script for HF Spaces.
*
* HF Spaces blocks DNS for api.telegram.org. This script intercepts
* globalThis.fetch() calls and redirects api.telegram.org requests
* to a working mirror (set via TELEGRAM_API_ROOT env var).
*
* This works because grammY (OpenClaw's Telegram library) uses Node 22's
* built-in fetch (undici), which bypasses dns.lookup monkey-patching.
* Intercepting at the fetch level is the only reliable approach.
*
* Loaded via: NODE_OPTIONS="--require /path/to/telegram-proxy.cjs"
