feat: add type hints and tests for DataFrame.from_records method- Add np_2darray support to data parameter type annotation- Add comprehensive tests for DataFrame.from_records in test_frame.py- Fix NumPy 2.0 compatibility in test (S1 instead of a1)- Test covers np.ndarray, list of tuples, pd.Index columns, and structured arrays- Addresses GitHub issue #1334
