inkhaven 1.3.2

//! 1.3.1 SUBMISSION-1 — `inkhaven submissions` subcommand.
//!
//! The structured submission tracker (the `.inkhaven/submissions.json`
//! sidecar via [`crate::submissions`]).  Add a submission, list the log,
//! move a record's status, or remove one.  The generated *drafts* live in
//! the `Submissions` system book; this tracks where they went.
