redesign ArchitectureSlide with island map aesthetic + turbopack dev

- Replace grid/SVG-line layout with archipelago map: organic island blobs,
  quadratic bezier sea routes, circular map-marker nodes
- Fix SVG distortion: all strokes use vectorEffect=non-scaling-stroke
- No more preserveAspectRatio=none diagonal-line warping
- LiteLLM hub gets spinning ring + ripple pulse on active
- Ocean background with per-tier radial glows, dot grid, zone labels
- Switch dev server to --turbopack for faster HMR
