.task-command was still using var(--status-success) (#28a745) which reads
muddy olive against the nebula gradient — the same dimming the status
pills and apps-installed pill already work around with #86efac. The
empty-state row ("$ No tasks found …") was the most visible offender.
Switches .task-command to the same bright mint already used elsewhere.
Same edit, while I was there: the empty-state copy interpolated
categoryName.toLowerCase() as `No ${cat} tasks found`, so the "All Tasks"
category produced "No all tasks tasks found". Special-cases the all
bucket and strips the trailing word when the category name already
includes it ("Running Tasks" → "No running tasks found", not "running
tasks tasks").
