WASI phase 4: --target wasi link driver and wasmtime smoke test #11379
Description
Part of #11375.
- new
--target wasiincrates/perry/src/commands/compile/targets.rs, emitting a.wasm - build
libperry_runtime.aforwasm32-wasip2(Tier-2, prebuilt std — no-Z build-std) - link with
wasm-ldagainst a wasi-sdk sysroot, then produce a component (wasm-component-ld/wasm-tools component new) - pin the WASI runtime version in
external-tools.json; smoke test: hello world, try/catch, a GC-heavy loop, a timer, a TCP round trip

Progress: #11413 landed.
perry compile --target wasinow links a runnable wasm32-wasip2 component: a wasm-ld link against a wasi-sdk sysroot, then component creation, with the WASI toolchain pinned.scripts/wasi_smoke.shruns six programs under wasmtime and diffs them against Node: values, closures/callbacks, classes, collections/JSON, generators/iterator helpers, andprocess.exit. All six match.Still open for this phase, from the smoke list above:

Done by #11413: perry compile --target wasi links a runnable wasm32-wasip2 component, with the toolchain pinned and scripts/wasi_smoke.sh running programs under wasmtime against Node. #12208 completed acceptance support.
