perf(app): reduce startup websocket work

Make provider catalogs compact and content-addressed so repeat launches can reuse the persisted snapshot instead of transferring it again. Remove eager global catalog loading and the stopped-agent defensive tail fetch, while keeping sequence-gap and reconnect recovery as the correctness paths. Add an opt-in production-ID Android profiling build for local startup traces.
