 - Change behavior of closed drivers:
     - Raise `DriverError` on using the closed driver.
     - Calling `driver.close()` again is now a no-op.
+- No longer implicitly closing drivers and sessions in `__del__()` (finalizer/destructor).
+  Make sure to call `.close()` on them explicitly or use them in a `with` statement.
