[BUG] /todos command duplicates output: "No todos currently trackedNo todos currently tracked"

What happened?

The built-in /todos slash command outputs its message twice, concatenated without any separator:

No todos currently trackedNo todos currently tracked

What did you expect to happen?

Should display "No todos currently tracked" exactly once.

Steps to reproduce

1. Open Claude Code in Terminal.app
2. Type /todos and press Enter
3. Output shows duplicated text: "No todos currently trackedNo todos currently tracked"
