CacheMaintenance prunes the SwiftData caches so they don't grow forever: seen markers >30d, read >90d, cached articles >30d, cached stories >14d — always protecting saved bookmarks. Runs on launch. Settings gains a "Clear offline cache" action (keeps saved) with a count + confirmation. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
