//! Runs started by hand are tasks.
//!
//! `magi run` and `magi review` used to mint a run no task knew about: no
//! detail page, no attempt history, invisible to duplicate detection, and an
//! orphan the moment anything cleaned up after it. They now file a task first,
//! through the queue like `magi task add`, and then either hand it to a live
//! loop or execute it here through the daemon's own attempt
//! ([`crate::daemon::run_claimed`]). There is no second dispatcher in this
//! module: it decides *who* runs the task and watches it, nothing more.
//!
//! * A live loop in another process (a fresh `daemon.json` heartbeat, see
//!   [`crate::daemon::foreign_loop`]) gets the task as `urgent`, runs it in
//!   its own urgent slot, and the caller [`follow`]s it. The caller never
//!   claims or executes it: two processes must not drive one task.
//! * Otherwise the caller claims the task **before it is written**, so a loop
//!   that starts mid-run finds the claim and leaves it alone, and executes it.
