* **New Features** * Plugin-style modules for platforms and devices with start/stop lifecycle and a runtime-consumable device tree array. * **Refactor** * Consolidated initialization into a kernel/module startup flow. * Generated devicetree artifacts moved to the build Generated directory. * **Changes** * Removed legacy no-op registration hooks and I2C lock/unlock wrappers. * Driver ownership and private state moved to explicit module/owner model. * Added ERROR_NOT_ALLOWED error code.
