What's Wrong?

Slash commands do not respond when typed in the Desktop app.
Typing /bug or /doctor in the message input and pressing Enter produces
no output, no error, and no visible reaction.

What Should Happen?

The /doctor command should run diagnostics and display results.
The /bug command should open a bug report form or prompt.
