V09: Mod source and target highlighting

Retained analysis
Clicking a source highlights its targets; hovering a target exposes contributing sources, and the same assignments appear as matrix rows. Use all three views to recover the actual graph after edits. The example separates Macro1->OSC1 frame from LFO1->Filter1 cutoff rather than treating both as one timbral motion.
Documentation and visible configuration; not a new native audio test. Project observations are distinct from the source author's claims.
