A from-scratch WebAssembly runtime in Zig.
Full WebAssembly 3.0 with 100% spec conformance. WASI 0.1 and 0.2 (Component
Model) in the released binaries; WASI 0.3 (native async) is served in full,
all six proposals against the official corpus, as an opt-in build tier
(-Dwasi=p3). Interpreter, JIT (arm64 and x86_64) and AOT backends,
differentially tested against each other. C, Zig and CLI surfaces. Green on
macOS aarch64, Linux x86_64 and Windows x86_64.
