Bug: `/stats` command prints nothing in TUI chat

What happened?

Reproduction steps: Run llamafile in --chat mode, then ask the model anything, and finally run /stats.

Nothing gets printed out in 0.10.x, but 0.9.x works fine and shows performance metrics (prompt eval and output token rate, etc.)

/help still lists the command, so I'm assuming this was supposed to still work, and wasn't removed.

Version

llamafile v0.10.5

What operating system are you seeing the problem on?

All platforms are likely affected (tested Windows 10, Linux Mint 22.3, and MacOS 15.7.9
