What's Wrong?

The /export command runs without errors but produces no output — the exported file is created but is empty, and the clipboard contains nothing when used in iTerm2.

Environment:

• OS: macOS Darwin 24.6.0
• iTerm2: 3.6.10

What Should Happen?

• Exported file and clipboard contain the full conversation transcript.

3-1. Run /export (clipboard variant) → outputs "Conversation copied to clipboard" but clipboard is empty
3-2. Run /export (file variant) → file is created but has 0 bytes
