/**
 * Decorator that clears the stack output cache when an app is destroyed.
 *
 * Without this, the cache file written during deploy would remain on disk after a
 * destroy, and a subsequent deploy (or any stack output read) would use it and behave
 * as if the stack were still deployed.
 *
 * The cache is cleared before the destroy runs. Since the cache is only a performance
 * optimization, this is safe even if the destroy fails and the stack remains: the next
 * read simply fetches fresh output from Pulumi again.
