"""Tests for the unified profile→machine dashboard launch routing.

`<profile> dashboard` routes to ONE machine-level dashboard instead of
spawning a per-profile server: attach (open browser at ?profile=) when one
is already listening, else re-exec as the machine dashboard with the
launching profile preselected. `--isolated` opts out.
