Daily monitoring tasks were pinned to a single primary client. If that
client went offline the task wedged even when another desktop client of
the same workspace was online and bound to the same account. Drop the
primary-client constraint on the materialized collect rows, and instead
pick a target per-platform from live account/client presence in Redis,
falling back to the DB client_id when the desktop client is still flagged
online. Desktop task lease for kind=monitor now matches by account
ownership in addition to target_client_id, so any client owning the
account can drain the queue.

Scheduler now runs a token-protected HTTP server on scheduler.http_port
(default 8081, -1 disables) that exposes Prometheus /metrics and the
daily-task JSON snapshot endpoint. Workers gain a blocking Run(ctx) and
are supervised by a WaitGroup: on SIGINT/SIGTERM the metrics server
shuts down first, worker ticks stop scheduling but ongoing runOnce
calls keep their own context and finish, and the process waits up to
60s before exiting. Adds scheduler.http_host/http_port/internal_metrics_token
to config with SCHEDULER_* env overrides and exposes port 8081 in the
Docker image.

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
Extract monitoring recovery/inspection workers and schedule dispatch
into a dedicated scheduler process. Add worker-generate process for
article generation and template-assist queue consumption. Introduce
shared/schedule runtime for cron-based worker lifecycle management.
