fa: wire GCWorker startup and shutdown in cmd/mediaplayer/main.go

- Refactor main into run(args) for testability and clean error propagation.
- Create slog.Logger from cfg.LogLevel using TextHandler.
- Instantiate service.NewGCWorker with store, clock, cfg.MediaRoot, and
  time.Duration(cfg.GCIntervalMinutes)*time.Minute.
- Start GCWorker after construction and defer Stop for graceful shutdown.
- Add cmd/mediaplayer/main_test.go as an integration smoke test wiring the
  GCWorker against a real SQLite store.
