netsuke-build 0.1.0-beta1

//! Tests for the CLI parser's localization rendering.
//!
//! Exercises locale-specific long-help output for the en-US and es-ES
//! locales, asserts that `--config <FILE>` and its Fluent-resolved
//! description are present, and pins the complete rendered help via Insta
//! snapshots to detect regressions in flag naming, ordering, or
//! localization drift.
