The bibtex-compatibility.py script was vulnerable to path traversal because it used sys.argv[1] directly to construct a file path without validation. This fix introduces input sanitization using os.path.basename() and adds a check for the number of command-line arguments to prevent potential crashes and unauthorized file access.


PR created automatically by Jules for task 13463926459918946299 started by @k4rtik

This commit addresses a security vulnerability where unvalidated command line
input could lead to potential path traversal. The script now:
- Checks if the required command-line argument is provided.
- Uses `os.path.basename()` to sanitize the input database name, ensuring
  that it cannot be used to access files outside the current directory.
- Gracefully exits with a usage message if arguments are missing.
