aider: aider: Modified cmd_add to skip file creation if word contains glob characters.

# Context:
USER: if word doesn't match anything, don't ask to add it if it contains glob characters
ASSISTANT: To implement this change, we need to modify the `aider/commands.py` file.

Here's the step-by-step process:

1. In the `cmd_add` method, before asking to create a file, check if the word contains any glob characters (`*`, `?`, `[`, `]`).
2. If it does, skip the creation process and print an error message.

Here's the code change:

```python
