* **New Features** * Thread API with lifecycle, priority, affinity and state monitoring * Timer subsystem: one-shot/periodic timers, reset, pending callbacks, expiry queries * Expanded I²C: register-level ops, bulk writes, presence checks, ESP32 integration and new config properties * GPIO controller: pin level and options APIs * Error utilities: new error code, error-to-string, timeout helper and common macros * Device construction helpers (construct+start) * **Tests** * New unit tests for thread and timer behavior * **Documentation** * Expanded coding style guide (files/folders, C conventions)
