Send-only Telegram mode (TELEGRAM_POLLING=false) for sharing one bot with another app (#2, @famewolf).
If Docksentry and another app (Home Assistant, say) both poll the same bot token, Telegram lets only one of them receive commands — the other loops on Conflict: terminated by other getUpdates request. Send-only mode makes Docksentry stop polling entirely (no getUpdates, no startup flush, no setMyCommands) while still sending its notifications, since sendMessage never conflicts. Let the other app own the interactive side and drive Docksentry from the Web UI.
Default stays true — nothing changes unless you opt in. Note this can't make two apps both interactive on one token; that's a hard Telegram limit.
