Telegram plugin crashes with 409 error due to orphaned polling processes on session restart
증상
The Telegram channel plugin (grammy-based long polling) crashes with a 409 Conflict error when a new Claude Code session starts, because the previous bot instance’s getUpdates polling loop is still running. This means the Telegram channel becomes unreachable after every session restart or /clear.
원인
Telegram Bot API conflict, rate limit, or webhook/polling configuration error causing message delivery failure.
해결법
Manually kill orphaned Telegram processes before starting a new session:
pkill -f "telegram/0.0.1"
