fix: fixed behavior for keyboard interrupts and user commands

[ErikBjare]

Has some similarities to https://github.com/ErikBjare/gptme/pull/371

---

[!IMPORTANT] Refactor keyboard interrupt and user command handling in chat.py and commands.py for consistent behavior.

• Behavior:
  • Refactor keyboard interrupt handling in chat.py and commands.py to use a consistent interrupt_msg.
  • Modify execute_cmd in commands.py to check both user role and command prefix.
• Functions:
  • Update step() in chat.py to yield interrupt_msg on KeyboardInterrupt.
  • Adjust handle_cmd() in commands.py to handle /help command separately.
• Misc:
  • Remove redundant assertions in execute_cmd() in commands.py.
  • Minor refactoring in chat.py to streamline message handling logic.

I need to break this apart to figure out why it isn't working
