Workflows often use multiple Fast Groups Muters with the matchColors
property, splitting groups into independent toggle scopes (e.g. one muter
for all blue-color groups, another for the gold "Flux Klein Workflow").
Previous Solo turned off widgets across ALL muters indiscriminately —
soloing a blue group would clobber the gold muter's state too, defeating
the user's intentional color-based partitioning.
Now: getMutersAndWidgets() returns per-muter widget maps. Solo finds the
single muter that owns the target group (via findMuterOwningGroup) and
toggles only within that muter's widget set. Other muters are left
exactly as the user set them. Reset still spans all muters (turn
everything on).
