Why
moonbitlang/async/stdiowas still native-only, so wasm users could not access standard input, output, or error through the async IO abstractions.What
This enables the internal stdio event-loop setup and public
stdiopackage on wasm, then adds a small handle-availability regression test.Why This Is Correct
The public
stdioAPI stays unchanged. The shared stdio setup still takes logical standard stream ids (0,1,2) like the native implementation. Upstream now always routes stdio through the thread pool, so wasm only needs a target-specificget_stdio_handle(id)import and the existing fd-kind import.Scope
This is limited to wasm stdio package support. Native stdio behavior is unchanged.
