mid-alloc

Custom memory allocators and layout management, including SpinLock<T> — a hand-rolled spinlock validated under real multi-threaded stress tests (8 real OS threads, thousands of increments each, zero lost updates). That same proven algorithm is the basis for mid-platform::sync::Mutex's own no_std fallback (an independent copy, not a dependency — see that crate's page for why).

Status: in progress; paused pending mid-arena updates.
