//! Aging threshold configuration helpers.
//!
//! Responsibilities:
//! - Resolve aging thresholds from queue config with defaults.
//! - Enforce strict threshold ordering before report computation.
//!
//! Not handled here:
//! - Per-task aging computation.
//! - Report assembly or rendering.
//!
//! Invariants/assumptions:
//! - Threshold ordering must remain `warning < stale < rotten`.
