cache

UDA declaring a per-resource / per-template draft CacheableResult freshness hint for a @resource- or @resourceTemplate-annotated method. The reflection layer plumbs it through to the matching low-level registration so a draft resources/read carries ttlMs / cacheScope. Has no effect on pre-draft protocol versions (the server only emits cache fields when negotiated to draft).

scope_ is "public" (the default) or "private".
