Interpreter direct native async yield-star does not adopt synchronous generator values #3667

Direct delegation from an interpreted async generator to a native synchronous generator yields the Promise object instead of adopting its value. A rejected promise therefore fulfills the outer next() and leaves the inner generator suspended.

const marker = {};
function* values() {
    try { yield Promise.reject(marker); }
    finally { console.log("inner finally"); }
}
async function* run() { yield* values(); }
async function main() {
    try {
        const result = await run().next();
        console.log("resolved", result.done, result.value === marker);
    } catch (error) { console.log("rejected", error === marker); }
}
main();

Interpreted output on unchanged baseline 0b44ff4de and after scoped PR #3663 review fix 774f626b4:

resolved false false

Current ECMAScript AsyncFromSyncIteratorContinuation requires value adoption and closing the non-final synchronous iterator on rejection, so the expected output is:

inner finally
rejected true

Node v22.23.2 prints rejected true; it adopts the promise but predates the newer close-on-rejection behavior, so current Test262 is the cleanup oracle.

Pinned Test262 d5e73fc8d2c663554fb72e2380a8c2bc1a318a33 case test/built-ins/AsyncFromSyncIteratorPrototype/next/yield-iterator-next-rejected-promise-close.js fails in the interpreted worker with:

Promise should be rejected Expected a Reject to be thrown asynchronously but no exception was thrown at all

SharpTSAsyncGenerator.DelegateYieldStarAsync directly handles iterable is SharpTSGenerator through DelegateGeneratorAsync; that branch bypasses the async-from-sync value adoption path. A custom iterable factory returning the same native generator uses the acquired iterator path and passes a new finally/error-identity regression in 774f626b4.

This is independent of the acquired custom iterator rejection cleanup fixed for review comment 4546709732. The emitted-adapter omission is separately tracked in #3666. No production fix was expanded into the direct-native branch during that scoped review correction.
