//! GPIO hardware access for autonomous agents.
//!
//! Provides safe, controlled access to GPIO pins with strict allow-lists,
//! auto-release on agent unhealthy, and direction change approval.
//! Uses `gpio-cdev` (modern character device API) as primary,
//! with `sysfs_gpio` as fallback for older kernels.
