Graph polish + one structural simplification, after the first render
of the combo-box layout:
* Leg names: every combination job's display name is now
'${{ matrix.tag.ref }} -> HEAD' - the box title (job id) already
carries os+methods, so repeating them per leg was noise. The inner
job renders as a short static 'e2e' tail (dynamic names render
unexpanded on skipped jobs, so it must stay static).
* The windows probe job is gone: pick-releases now annotates each
picked tag with whether its tree ships apps/desktop
({ref, desktop} objects in the matrix), and the windows run
workflow gates on the new tag-has-desktop boolean input directly.
One tree listing at pick time replaces N probe jobs, and the
'probe tag' noise disappears from the graph.
Annotation loop verified against the real tag set (pre/post-desktop
split lands exactly at the app's introduction); 16-combo inventory
re-asserted; all four workflows pass actionlint.
