Add fast-path checks in process_to_add(), cleanup_(), and process_defer_queue_() to skip mutex acquisition when there is nothing to process. Uses std::atomic<uint32_t> counters on platforms with atomics support (ESP32, host), falls back to always taking the lock on platforms without atomics (LibreTiny). Single-threaded platforms (ESP8266, RP2040, nRF52) check directly since there are no concurrent writers. Also migrates existing to_remove_ to the same atomic pattern and moves the defer_queue_.size() snapshot under the lock — both were previously plain reads without the lock while being modified cross-thread.
