Asgard v0.6.0 is a task runner for any kind of project, with tasks written in Ruby. This release adds background jobs: sh "mkdocs serve", background: true starts a process that keeps running after asgard exits and logs its output, and asgard jobs list|stop|log|restart|clean manages those processes. A shells registry (shell, default_shell) picks the interpreter every sh runs under. 0.6.0 requires Ruby 4.0+ and has breaking changes: if you use schedules or the watcher, remove and stop them with the old version still installed, then upgrade, then reinstall and restart them.
