ywkang e94f1de078 Cube-view SVG: detailed topology validation rendering
- Dedicated cube_view renderer showing 6×6 router grid with attachments
- PE blocks drawn next to their router (above/below)
- HBM pseudo channel port bar (64 ports, color-coded by PE owner)
- Per-PE BW annotations on HBM links
- Router color-coded by type (PE/M_CPU/SRAM/UCIe/relay)
- Title shows mode, channel count, per-PE and total BW
- Legend for all component types
