socket-patch-cli 3.2.0

//! Top-level `Cli::try_parse_from` behavior tests.
//!
//! These tests cover the parser surface that doesn't fit in
//! `src/lib.rs::tests` — clap's auto-generated help/version handling, the
//! "no subcommand" error kind, every subcommand name, and the
//! visible_alias values (`download` for `get`, `gc` for `repair`).
//!
//! Each subcommand name and alias here is part of the CLI contract
//! defined in `crates/socket-patch-cli/CLI_CONTRACT.md`.
