fix(workspace): give the Overview nav entry its own home glyph

Overview reused the concept's Activity pulse byte for byte, so once the
Activity row lands two entries would share one icon. Overview now has an
outline home glyph. The shell comparison takes it from the D28 ruling
instead of the concept's activity path, and the icon test checks that
every approved glyph is distinct.
