shigoto 0.1.2

//! shigoto (仕事) — the typed job-system primitive.
//!
//! Umbrella crate. Re-exports the public surface of every sibling so
//! consumers depend on `shigoto = "0.1"` and reach the full algebra
//! via `use shigoto::{Job, JobId, Scheduler, ...};` without naming
//! every sub-crate.
//!
//! Canonical spec: `theory/SHIGOTO.md`.
//! Theory frame: `theory/THEORY.md` §IV (Motion).
