 * Yield a value (or promise, or nested promise) and recover it with its fully
 * unwrapped type. Use with `yield*` so the call site reads as
 * `const x = yield* awaited(client.all(...))` with no per-yield cast. In sync
 * mode the value passes through unchanged; in async mode the driver awaits it
 * before resuming. `Awaited<T>` collapses any level of `Promise<>` so this is
 * safe to use with `client.transaction(...)`'s `T | Promise<T>` overload union.
