"""Dataflow helpers and transformation utilities.

This module provides reusable operators for data transformations:
- text: Text processing and manipulation
- table: Tabular data operations
- json: JSON schema validation and transformation
- sampling: Sampling and filtering utilities

These are pure-Python utilities with no engine dependencies.
