systemprompt-loader 0.6.1

//! Reads, validates, and writes profile YAML files (with embedded
//! gateway / cloud catalogues).
//!
//! [`ProfileLoader`] is a thin shim over
//! [`systemprompt_config::load_profile_with_catalog`] that adds:
//!
//! - on-disk path conventions (`profiles/<name>.secrets.profile.yaml`),
//! - serialization with a leading "do not commit secrets" header, and
//! - directory enumeration for the `systemprompt cloud` CLI commands.
