//! Memory management and OOM prevention.
//!
//! Provides cgroup-aware memory tracking with backpressure signals
//! for Kubernetes-deployed services. Prevents OOM-kills by applying
//! backpressure before hitting the container memory limit.
//!
//! # Architecture
//!
//! ```text
//! Layer 1 (opt-in): Cap allocator -- hard limit, last-resort crash instead of OOM-kill
//! Layer 2 (default): MemoryGuard -- cgroup-aware tracking, backpressure signals
//! ```
