docs: gather panel design prototypes into docs/prototypes/
I gathered all five self-contained HTML/CSS design prototypes into one home: the instrument-console pair (moved from assets/), plus the net-panel rescan, sound panel, widget gallery, and waybar redesign (moved out of working/). Added a README index and updated every inbound link: build summary, the instrument-console and audio specs, and todo.org. Also fixed a broken link the earlier sort left in the build summary. It still pointed at the instrument-console spec's old docs/design/ path after the move to docs/specs/.
