Add pcb silkscreen graphic support

[techmannih]

Summary

• add a SilkscreenGraphic primitive component for BRep-based PCB silkscreen graphics
• teach createComponentsFromCircuitJson to reconstruct pcb_silkscreen_graphic elements from circuit JSON
• cover the round-trip with a PCB snapshot test

Why

• allow circuit-json silkscreen graphics to round-trip back into core components

Impact

• users can import BRep silkscreen graphics from circuit JSON and render them through the existing PCB snapshot flow

Validation

• bun test tests/utils/createComponentsFromCircuitJson/pcb-silkscreen-graphic-snapshot.test.tsx
• bunx tsc --noEmit

using a fast-xml-parser to parse the imported SVG image so we can extract its shapes, transforms, and fill rules, convert them into paths/polygons, and then generate internal BRep pcb_silkscreen_graphic geometry
