//! Generates Python type stub files (.pyi) for the term_maths extension module.
//!
//! Run with:
//!
//! ```sh
//! cargo run --features python --bin stub_gen
//! ```
//!
//! The stubs are written to `python/term_maths/_term_maths.pyi` (relative to
//! the workspace root). The output path is determined automatically by
//! pyo3-stub-gen by scanning upward for `pyproject.toml`.
