Don't send invalid /<commands> to the server

[klxdev]

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 15.4.0 (24E248)

Expected behaviour

When provided a / that doesn't exist of is misspelled, don't send this request to the LLM. Just reply with command not found and let me know that I should use /help

Actual behaviour

I mistyped /clear with /claer accidentally and I have to wait 20 seconds+ for the server to return for no reason. I also could not CTRL+C to stop this.

Steps to reproduce

Type a misspelled of non-existent command and hit enter in the chat.

It's already fixed, isn't it?
When the wrong command is entered the following message appears and there seems to be no access to the server.

Error: Unknown command: '/claer'. Type '/help' to see available commands.
To use a literal slash at the beginning of your message, escape it with a backslash (e.g., '\//hey' for '/hey').
