aider: Moved the import statement for the glob module to the top of the aider/commands.py file.

ASSISTANT: The error message indicates that the `glob` module is not defined in the `cmd_add` method of the `Commands` class in the `aider/commands.py` file. This is because the `glob` module is imported inside the `Commands` class, but it should be imported at the top of the file.

Here are the changes you need to make:

```python
aider/commands.py
<<<<<<< ORIGINAL
import json
import os
import shlex
import subprocess
import sys

import git
import tiktoken
from prompt_toolkit.completion import Completion

from aider import prompts, utils

class Commands:
    import glob
=======
import json
import os
import shlex
import subprocess
import sys
import glob

import git
import tiktoken
from prompt_toolkit.completion import Completion

from aider import prompts, utils

class Commands:
>>>>>>> UPDATED
```

This change moves the `import glob` statement from inside the `Commands` class to the top of the file, which is the standard place for import statements in Python. This will make the `glob` module available to all methods in the `Commands` class.
