86c2842CompareFixes#1185. If a routine was halted while suspended inside scoped(), code after yield* scoped(...) would still run. iter.return() yielded the destroy() effects in scoped's finally, but the resume came back as iter.next() — which takes the frame out of return-mode. trap() re-arms via trap.exit(); scoped() had no equivalent. Pre-d3266784 the Delimiter handled this with a sticky "cancelling" state; the unify refactor lost it. Fix: inline the Trap, run destroy() in critical() so cleanup completes, then yield trap.exit() to re-arm unwind based on the inner trap's outcome.

Motivation
Fix#1185.
If a routine was halted while suspended inside scoped(), code after yield* scoped(...) would still run.
iter.return() yielded the destroy() effects in scoped's finally, but the resume came back as iter.next() which takes the frame out of return-mode. trap() re-arms via trap.exit(); scoped() had no equivalent.
Fix: inline the Trap, run destroy() in critical() so cleanup completes, then yield trap.exit() to re-arm unwind based on the inner trap's outcome.
