Task groups - Githubissues

// NOTE: whitespace in name
task("build front", async () => { /* build frontend */ } )
task("build back", async () => { /* build backend */ })

It'll then be accessed by...

$ ghjk x build front
$ ghjk x build back

If only ghjk x build, is invoked, list the available tasks.
On ghjk x build --run, run all tasks under it in parallel.
If another task is explicitly defined under the name build, it overrides this group header task.

Consider alternative semantics used by mise.
