//! runtime.zig — a **compatibility shim** for the runtime split (reorg C1–C5).
//!
//! `library/runtime` became `library/kernel`, and the one giant `runtime` module is being
//! split into directly-importable concern modules (`ipc`, `memory`, `process`, `time`,
//! `logging`, `file-system`, `service`, `thread`, `start`, plus the device/service clients).
//! This file re-exports those modules under the old `runtime.*` names so the ~38 consumers
//! keep compiling until each is migrated to direct imports. Deleted in step C5.
