//! `clauth login`'s hand-rolled arg parsing. `parse_login_args` is a pure
//! shape check, so it's exercised directly; `dispatch`'s success arm for a
//! *valid* `--model` shape calls `cmd_login`, which spawns a real `claude`
//! process via `start::run` and is never exercised here. Model persistence
//! itself is covered in `tests/inline/actions.rs` (`set_profile_default_model`).
