This change adds `bigframes.bigquery.rand()` which wraps the BigQuery `RAND()` function. It accepts a Series or DataFrame as input to determine the shape and index of the output Series. It includes a warning about non-determinism in the docstring. Tests are added in `tests/unit/bigquery/test_mathematical.py` and `tests/system/small/bigquery/test_mathematical.py`.

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

This change adds `bigframes.bigquery.rand()` which wraps the BigQuery `RAND()` function. It accepts a Series or DataFrame as input to determine the shape and index of the output Series. It includes a warning about non-determinism in the docstring. Additionally, `SqlScalarOp` has been updated to accept an `is_deterministic` argument, which is set to `False` for `rand()`. Tests are added in `tests/unit/bigquery/test_mathematical.py` and `tests/system/small/bigquery/test_mathematical.py`.
