WASI 0.3.0 Released

The WASI Subgroup has officially ratified WASI 0.3.0, rebasing WebAssembly System Interface onto the WebAssembly Component Model's native async primitives. This update eliminates the need for workarounds previously required in WASI 0.2, allowing developers to write asynchronous code more ergonomically through simplified interfaces for I/O, sockets, and networking. Key changes include replacing manual polling patterns with native futures, removing capability resources, and consolidating start/finish function pairs into single async functions.
