Node labels were coloured by marker type (self yellow, repeater
violet, leaf pink); they now carry the app-wide key-derived name hue —
MapMarker grows a key field threaded from contacts, stored heard
nodes, and self-info — with our own label the pure you-white while the
★ glyph keeps its yellow. Find-filter matches still force full white,
non-matches still dim bare. The CLI legend follows suit (and its SEEN
column header becomes HEARD, per the lexicon).
