//! `kata register [<path>] [--name N] [--tags ...]` — record a
//! kata-managed project in the global registry
//! (`~/.config/kata/config.toml`).
//!
//! The registry is a *pointer* layer: kata never reads templates
//! through it (that's `applied.toml`'s job per-PJ), but it gives
//! `kata list --all` / `kata apply --all` a list of PJs to walk
//! when the user wants a multi-PJ overview.
