refactor(main): the sweep takes one AppContext instead of five collaborators

periodic_sweep listed sender, chat_store, link_cache, task_queue and config as separate parameters — exactly the five fields AppContext already carries, and exactly what handle_message and the workers pass around as one value. It takes &AppContext now (production via from_statics(&bot), the test via stores.ctx(&sender), which that test already had); CHAT_STORE and LINK_CACHE lose their last direct use in main and leave the import. The collaborator bundle is unchanged, so the paused-clock test drives the same loop.
