Native SVG Import/Export for p5.js via p5.Shape System (custom Project)

This project aims to add native SVG import and export capabilities to p5.js through enhancements to the p5.Shape system. Currently, p5.js only supports raster exports which limits professional workflows for artists and educators who require vector outputs. The project will first extend the Shape system by adding ArcSegment and EllipseSegment primitives to enable structured geometry recording. Then an SVG export add-on will be developed using a visitor pattern to convert recorded primitives into clean SVG paths with transform support. Key deliverables include a shape recording API, SVG export via saveSVG(), basic SVG import support, documentation, and tests. This will improve interoperability of p5.js with design tools and vector workflows while maintaining backwards compatibility.
