Integrate shell command execution in CLI and autocomplete support

In this commit, we've added a new feature to our CLI in `aicodebot/cli.py` that allows users to execute shell commands directly. This is done by typing `/sh` followed by the desired command. We've also ensured that empty commands are handled gracefully.

In addition, we've updated the autocomplete functionality in `aicodebot/coder.py` to include the new `/sh` command. This will provide a smoother user experience when using the CLI. 🚀👩‍💻
