Tab5 power expander driver and devicetree parsing improvements (#507)
* **New Features**
  * PI4IOE5V6408 I2C I/O expander driver with public GPIO APIs
  * CLI tool to list devicetree dependencies

* **Device Tree Updates**
  * M5Stack Tab5 configured with two I2C IO expanders; PI4IOE5V6408 binding added

* **Build / Tooling**
  * Devicetree code generation integrated into build; generated artifacts and dynamic dependency resolution exposed

* **Refactor**
  * Kernel/run APIs updated to accept a null‑terminated devicetree modules array; many module symbols renamed

* **Documentation**
  * Added README and Apache‑2.0 license for new driver module

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.

Implement support for module symbols (#475)
* **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.

Rename device modules (#470)
Standardised device module identifiers across all supported devices to use consistent naming conventions with lowercase alphanumeric and hyphen-separated formats.

Kernel improvements (#468)
* **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.
