//! `slu each <git args>` — run any git command in every repo under the current
//! directory, in parallel.
//!
//! This generalizes the dedicated multi-repo commands: `slu each pull --ff-only`,
//! `slu each "log --oneline -1"`, `slu each switch main`. Whatever you'd type
//! after `git`, it runs in each repo and prints the output grouped per repo.
