//! `netsky nap <seconds>` — write the quiet sentinel before a long
//! harness-owned ScheduleWakeup.
//!
//! The harness still owns the actual sleep primitive. This command
//! closes the memory-gated part of the contract: for naps long enough
//! to collide with the pane-stable detector, it writes the sentinel and
//! prints the exact ScheduleWakeup arguments to use next.
