[BUG] [UX] Claude stops responding mid-task with no feedback - stuck for 10+ minutes

Preflight Checklist

• [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?

Claude Code stopped in the middle of a task and became completely
unresponsive for over 10 minutes. There is no spinner, no status
message, and no indication of what is happening. The "Ask" button
remains disabled, so the user cannot send new messages or cancel.

Claude's last message was: "Saya sudah mendapatkan base64 dari logo.
Sekarang saya akan mengupdate fungsi addLogoOverlay untuk menggunakan
logo asli ini sebagai gambar overlay..."

After this message, nothing happened for 10+ minutes.

What Should Happen?

• If Claude is still processing: Show spinner with status message
• If Claude is stuck: Show error message or timeout warning
• If task is complete: Show the result
• Allow user to cancel or send new message
