test(telegram): cover autoSelectFamily env precedence

CHANGELOG.md

@@ -64,6 +64,7 @@ Docs: https://docs.openclaw.ai
 - Telegram: ignore `<media:...>` placeholder lines when extracting `MEDIA:` tool-result paths, preventing false local-file reads and dropped replies. (#18510) Thanks @yinghaosang.
 - Telegram: skip retries when inbound media `getFile` fails with Telegram's 20MB limit and continue processing message text, avoiding dropped messages for oversized attachments. (#18531) Thanks @brandonwise.
 - Telegram: clear stored polling offsets when bot tokens change or accounts are deleted, preventing stale offsets after token rotations. (#18233)
+- Telegram: enable `autoSelectFamily` by default on Node.js 22+ so IPv4 fallback works on broken IPv6 networks. (#18272) Thanks @nacho9900.
 - Auto-reply/TTS: keep tool-result media delivery enabled in group chats and native command sessions (while still suppressing tool summary text) so `NO_REPLY` follow-ups do not drop successful TTS audio. (#17991) Thanks @zerone0x.
 - Agents/Tools: deliver tool-result media even when verbose tool output is off so media attachments are not dropped. (#16679)
 - Discord: optimize reaction notification handling to skip unnecessary message fetches in `off`/`all`/`allowlist` modes, streamline reaction routing, and improve reaction emoji formatting. (#18248) Thanks @thewilloftheshadow and @victorGPT.
