//! Parallel orchestration facade.
//!
//! Responsibilities:
//! - Re-export the direct-push parallel run-loop entrypoint.
//! - Keep preflight, main-loop control, and shutdown/finalization separated.
//!
//! Not handled here:
//! - Parallel state persistence format.
//! - Worker spawn/monitor implementation details.
//!
//! Invariants/assumptions:
//! - Queue lock ownership stays with the orchestration entrypoint for task selection safety.
