[Bug] Telegram plugin not receiving messages due to missing --channels flag implementation

Bug Description
Telegram plugin connects but does not receive messages.

Logs show:
"connected with subscribe=false"
"Channel notifications skipped: plugin not in --channels list"

However:

• claude --help shows no --channels flag
• cannot enable channels manually

Result:
Bot shows "typing" but Claude session never receives messages.

This appears to be a mismatch between Telegram plugin and Claude Code CLI (v2.1.81).

• Platform: darwin
