//! Writes `config.example.toml` at the repository root from the settings
//! catalogue.
//!
//! A binary rather than a build script for the same reason `plugmem-py`'s
//! `stub_gen` is one: the artifact is committed, so a human runs this and
//! commits the result, and CI fails on the difference. A build script would
//! rewrite the file during every unrelated build and turn an honest gate into
//! a dirty working tree.
