//! system.zig — a **compatibility shim**, not the real home of anything anymore.
//!
//! The runtime's syscall surface used to be dumped here in one file. It has been split by
//! concern into `time` / `logging` / `process` / `file-system` / `memory`. This re-exports
//! the old flat `system.*` names from those homes so consumers that still write
//! `runtime.system.write` (etc.) keep compiling until they migrate to the concern modules.
//! Deleted once nothing references `runtime.system` (reorg step C5).
