kasl-cli 1.10.0

//! Commands must work, or fail cleanly, with no terminal attached.
//!
//! kasl runs from scripts, cron jobs and the watch daemon, none of which can
//! answer a prompt. Every command here is spawned as a real process with stdin
//! detached, because that is the only way to reproduce the condition that made
//! `task add --name X` panic on a prompt nobody could see.
