Claude Code hangs after 'git rebase origin/main' completes

Description

Claude Code instance becomes completely unresponsive after running git rebase origin/main command, even though the rebase completes successfully.

Reproduction

1. Run git rebase origin/main through Claude Code (either directly in bash tool or as part of a plan)
2. Wait for rebase to complete
3. Instance hangs and becomes unresponsive

Details

• Exact command run: git rebase origin/main
• Reproducibility: Consistent - happened twice today at the same point
• Rebase status: Command completes successfully (verified with git status showing rebased commits)
• Instance state: Completely unresponsive - cannot interrupt with Ctrl+C, cannot run new commands
• Recovery: Only way to recover is to kill the window entirely

Expected Behavior

After a bash command completes, the Claude Code instance should remain responsive and ready for new commands.

Environment

• Platform: Windows
