//! `runtime repo` — list / view / clone.
//!
//! `list` returns repositories visible to the configured account
//! (filtered down to those whose `ownerSlug` matches the configured
//! username for the "my repos" feel). `view` prints the repo's
//! metadata. `clone` shells out to `git clone` with the HTTPS URL
//! derived from the configured host (`<host>/<owner>/<name>.git`).
