Sfsym: Extract Apple SF Symbols as Standalone Vectors

Sfsym simplifies macOS development workflows by enabling direct vector export of Apple's SF Symbols without requiring Xcode or SF Symbols.app dependencies. The tool reads vectors directly from macOS's native renderer, ensuring pixel-perfect accuracy across SVG, PDF, and PNG output formats. This is particularly valuable for developers and designers needing to integrate Apple's design system icons into documentation, prototypes, and cross-platform tooling while respecting the SF Symbols license.
