* **Improvements**
* Unified, simplified module registration across build targets
* Tests updated to reflect new module lifecycle and global symbol resolution
* **Export more symbols:**
* Expanded standard library support with additional math functions (trigonometric, exponential, and rounding operations), string comparison, directory operations, and locale configuration
* Added C++ static initialization guard utilities to enhance object initialization support
* **New Features**
- Adds module symbol support and per-module symbol tables, including LVGL symbol exports moved into a dedicated table.
* **API**
- Adds symbol-resolution APIs and an accessor to enable dynamic lookup between modules.
* **Bug Fixes / Chores**
- Explicitly initializes module symbol pointers across device and platform modules to avoid uninitialized state.
* **Tests**
- Updates tests to account for symbol pointer initialization.
* **New Features**
* Added a standalone LVGL module and enabled LVGL support in the simulator for richer local UI testing.
* **Refactor**
* HAL and LVGL split into distinct modules; startup and device attach/detach flows reorganized for clearer lifecycle management.
* Public APIs tightened with clearer nullability/documentation.
* **Bug Fixes**
* More consistent LVGL start/stop and device attach/detach behavior for improved stability.
* **New Features**
* Added a HAL device module providing device enumeration, type queries and a HAL↔kernel bridge.
* **Improvements**
* Integrated HAL module into startup; standardized module names, includes and lifecycle logging; safer file append behavior; broader build support.

* Updated tests and object file handling to behave correctly.
Standardised device module identifiers across all supported devices to use consistent naming conventions with lowercase alphanumeric and hyphen-separated formats.
* **New Features**
* Added a GPIO hardware abstraction layer for reading pin levels from applications.
* Applications can now query the number of available GPIO pins so they can adapt to different devices.
* **Chores**
* Integrations updated so GPIO capabilities are discoverable and exported to running applications.
* **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.
