[BUG] UI hangs in 'accept edits' mode after streaming abort - WSL2

[pentafive]

Preflight Checklist

• [x] I have searched existing issues and this specific symptom hasn't been reported
• [x] This is a single bug report
• [x] I am using the latest version of Claude Code

What's Wrong?

After a streaming request was aborted (user interrupt), Claude Code entered an unrecoverable state where:

1. UI shows "⏵⏵ accept edits on (shift+tab to cycle)" at bottom
2. Keyboard input is completely ignored (Esc, y, n, Enter, Ctrl+C - nothing works)
3. Session appears frozen but timer continues (showed 26s+)
4. Only way to exit was closing terminal

What Should Happen?

After streaming abort, Claude should gracefully recover and return to accepting user input.

Additional observations:

• Session continued processing after error but UI was frozen

1. Start Claude Code session with active todo list

4. Attempt any keyboard input - nothing responds

Related but distinct from #10484 - same error but different trigger (user abort vs @ folder) and symptom (UI hang vs crash).
