netspeed-cli 0.10.2

//! Raw CLI input types that bridge the CLI layer to the config layer.
//!
//! These structs carry unmerged, unvalidated values from [`crate::cli::Args`].
//! The only place that touches `Args` directly is `ConfigSource::from_args`;
//! everything downstream depends on these source types, not on the CLI crate.
