[BUG] Cannot disable built-in "Claude is waiting for your input" iTerm notification (macOS)

What's Wrong?

After a few seconds of being idle, Claude Code automatically sends an iTerm2 notification saying "Claude is waiting for your input". I never enabled this notification and I haven't found a way to disable it.

I cannot turn off iTerm2 notifications globally because I rely on other notifications from different applications. I haven't found a setting in settings.json or config option to disable this specific Claude Code notification.

What Should Happen?

Notifications I didn't configure should either not appear, or there should be a way to disable them.

Steps to Reproduce

1. Open iTerm2 on macOS with Terminal notifications enabled (Preferences → Profiles → Terminal)
2. Start Claude Code
3. Let Claude finish a task and wait a few seconds
4. An unsolicited iTerm notification "Claude is waiting for your input" appears
5. There is no obvious setting to disable this
