[Bug] /memory menu cannot be dismissed after selecting a memory location

Bug Description

Steps to reproduce:

1. Run /memory command
2. Select a memory location (e.g. "Project memory")
3. Press Esc to cancel — the menu does not close

Expected behavior: Pressing Esc dismisses the /memory menu

Actual behavior: Pressing Esc outputs ^[^[^[^[^[ characters instead of closing the menu, leaving the UI stuck
