//! Single-status (always open) ready-queue rendering.
//!
//! Shape matches `bl list`'s flat mode so the eye doesn't retrain
//! between commands: priority dot + status glyph + status word + id +
//! claimed badge + title + tags. The new piece here is the parent
//! hint — `↑ bl-xxxx (title)` rendered dim — appended when a task
//! has a parent, so an agent picking work from `bl ready` doesn't
//! lose the surrounding epic.
