Bug: Memory menu becomes unresponsive after showing user memory

Description

When the memory menu pops up and shows "User memory ✓", the interface becomes unresponsive to keyboard input. The terminal shows garbled characters like ^[[B^[[B^[[A^[[A^[[A^[[ instead of responding to Enter/Esc keys.

Steps to Reproduce

1. Trigger the memory feature in Claude Code
2. The memory menu appears showing:

• User memory ✓
• Project memory
• Open auto-memory folder

1. Try to press Enter to confirm or Esc to cancel
2. Interface is unresponsive and shows escape sequences

Expected Behavior

• Enter key should confirm the selection
• Esc key should cancel the operation
• Arrow keys should navigate between options

Actual Behavior

• Keyboard input produces escape sequences (^[[B, ^[[A, etc.)
• Menu remains stuck and cannot be dismissed
• Requires Ctrl+C to exit

Environment

• Claude Code version: [please fill in]
• Terminal: [please fill in]
• OS: [please fill in]

Additional Context

The issue occurs specifically after "User memory" is shown with a checkmark, suggesting the state transition may be interfering with input handling.
