Introduce a generic read-through caching infrastructure and wire it into all major tenant app services to reduce database load on hot read paths. Key changes: - Add `DeletePrefix` to Cache interface with memory (prefix scan) and Redis (SCAN + DEL) implementations - New `readthrough.go`: generic `LoadJSON` / `LoadJSONWithEmpty` helpers backed by singleflight to prevent cache stampedes; supports jittered TTL - New `cache_support.go`: centralized cache key builders and invalidation helpers for all entities (workspace, brand, prompt rules, schedule tasks, articles) - Wire optional cache into ArticleService, BrandService, WorkspaceService, PromptRuleService, ScheduleTaskService, TemplateService, MediaService, PromptGenerateService via `WithCache()` builder pattern - ScheduleDispatchWorker invalidates schedule task cache after dispatching - ArticleService gains a new `Detail` endpoint with empty-result caching - Update cmd entrypoints and transport handlers to propagate cache
