WASI 0.3.0 brings native async to WebAssembly

WASI 0.3.0 solves one of WebAssembly's largest remaining hurdles for server-side dominance. Bringing native async support means WebAssembly can finally handle highly concurrent, I/O intensive cloud workloads efficiently, making it a viable alternative for microservices and edge computing. The successful integration of futures and streams proves the maturity of the WebAssembly Component Model, solidifying it as the foundational architecture for the Wasm ecosystem moving forward. By allowing seamless interoperability between different languages' async/await paradigms without heavy glue code, this release will drastically accelerate the adoption of Wasm by simplifying development for cross-language toolchains.
