//! Fuzz target for profile YAML parser.
//!
//! This target tests INV-8 (no panic at public boundary) for the profile YAML loader.
//! Any panic indicates a YAML parser bug that must be fixed.
//!
//! The target exercises:
//! - YAML parsing via serde_yaml
//! - Profile structure validation
//! - Secret key detection (forbidden keys like 'password', 'api_key', etc.)
