The runtime_stats component used a std::map<Component*, ComponentRuntimeStats> to record per-component timing data. Every loop iteration for every component required a red-black tree lookup to record its time, adding ~2-3µs of measurement overhead per component — often exceeding the actual work done by lightweight components like OTA idle checks. Move RuntimeStats struct directly onto Component (behind #ifdef USE_RUNTIME_STATS) so recording is a direct member access with zero lookup cost. The RuntimeStatsCollector now iterates App.components_ to collect stats instead of maintaining its own map, eliminating ~2KB of red-black tree code.
