fix: Address pylint warnings in _local_server.py

- Use 'with' statements for resource management where appropriate
- Add explicit exception chaining with 'from e'
- Replace broad Exception catches with specific exceptions (OSError, URLError)
- Add pylint disable comment for subprocess.Popen usage where 'with' is not suitable
