[BUG] Windows Terminal - Persistent terminal notifications during bugged/looped session (persists when chat resumed also)

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

After resuming a Claude Code chat session that previously experienced a stuck/looping state (repeatedly returning React Server Components data instead of API results), a persistent notification plays whenever any action is taken in Windows Terminal. The notifications persist even after:

• Clearing Windows Action Center notifications
• No background processes or notification-related processes running

What Should Happen?

There shouldn't be any notifications at all. I have had to manually remove notifications from my Powershell profile because any actions would trigger it.

N/A

Steps to Reproduce

1. Start a Claude Code session and execute commands that trigger API requests (e.g., multiple curl commands)
2. Experience a session that gets "stuck" in a loop (in this case, repeatedly getting React SSR data instead of expected API responses)
3. Session got stuck in a loop of loading the user prompt, indicating actions were being taken by Claude Code, and repeating over and over.
4. Resume the chat session later
5. Notice persistent notifications in Windows Terminal on any action performed.

Additional Information

• The issue started when Claude Code went into the aforementioned loop
• It also specifically happens after resuming the same chat that had experienced looping API responses, even though it's no longer stuck in a loop
• The original loop was caused by curl requests returning React Server Components data instead of JSON API responses
• No error messages or logs are visible
• Sound notifications were successfully disabled via shell profile, but the visual icon persists
