yak-swc: SWC Plugin for next-yak CSS-in-JS

yak-swc is a Rust-based SWC (Speedy Web Compiler) plugin designed to compile CSS-in-JS code at build time, specifically for projects using `next-yak`. It transforms `next-yak`'s styled components syntax into optimized CSS, leveraging SWC's performance for faster build times. The current stable version is 9.4.1, with patch and minor releases aligning with the `next-yak` ecosystem, indicating an active development and release cadence. A key differentiator is its Rust implementation for high performance, allowing build-time CSS extraction, and its separation from the main `next-yak` package to ensure compatibility with specific `@swc/core` versions. This plugin is crucial for achieving zero-runtime CSS-in-JS with `next-yak` in environments leveraging SWC.
