rippy-cli 0.1.2

//! Preconfigured safety packages — named rule bundles for different workflows.
//!
//! Packages are embedded TOML files that slot between stdlib and user config.
//! They provide sensible defaults for common development scenarios so users
//! can get started with a single `package = "develop"` setting.
//!
//! Three packages are available:
//!
//! - `review`    — full supervision, every command asks
//! - `develop`   — auto-approves builds, tests, VCS; asks for destructive ops
//! - `autopilot` — maximum AI autonomy, only catastrophic ops blocked
