Acceptance criteria

• Canonical ABI lifting and lowering covers Preview 3 draft future and stream values across native, web, and node runtime paths.
• Ownership, borrowing, and lifetime behavior integrates with the runtime resource model without leaking handles or trapping spuriously.
• Focused tests cover successful transfers plus closure, error, and cancellation-adjacent paths.
