Kernel improvements (#485)
* **New Features**
  * Added public accessors for querying module/device start and ready state.

* **Refactor**
  * Internal state moved to opaque internal objects; module/device/driver initializers now explicitly initialize internal pointers.
  * Lifecycle handling updated to construct/destruct internal state and use accessors.

* **Tests**
  * Tests updated to use public accessors and explicit construct/destruct lifecycle calls.

* **Chores**
  * Test build/include paths and small metadata updated.
