Add kernel drivers for SPI and UART and make locking APIs more consistent (#489)
- Add kernel support for SPI driver
- Add kernel support for UART driver
- Implemented ESP32 UART kernel driver
- Update existing UART-related code in Tactility to use new kernel driver
- Remove UART from tt::hal::Configuration
- Remove tt_hal_uart functionality but keep functions for now
- Update devicetrees for UART changes
- Kernel mutex and recursive mutex: improved locking API design
- Other kernel improvements
- Added device_exists_of_type() and device_find_by_name()

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.

I2S driver implementation (#480)
* **New Features**
  * ESP32 I2S controller support: runtime-configurable digital audio I/O with read/write/set/get operations and multiple formats.

* **Board Support**
  * LilyGO T-Deck device tree entry added to enable I2S peripheral pin configuration.

* **Documentation**
  * New/updated bindings and descriptors for I2S, I2C, GPIO, and root nodes.

* **Other**
  * Added GPIO "no pin" sentinel and exposed I2S controller API symbols.

Kernel and TactilitySDK improvements (#479)
* **New Features**
  * Expanded public device and driver APIs (accessors, sync, lifecycle, binding) and a module construct+start helper.
  * Added kernel symbol registry and new exported symbols (lvgl, C++ nothrow, I2S APIs, additional math funcs).

* **Refactor**
  * Renamed device traversal APIs for consistency (device_for_each*).
  * Moved inline helpers to explicit public declarations.

* **Chores**
  * Replaced several shell release scripts with Python-based SDK release tooling.
* **Style**
  * Header naming consistency fixes.

Kernel and buildscript improvements (#477)
* **New Features**
  * Centralized module management with global symbol resolution
  * Level-aware logging with colored prefixes and millisecond timestamps

* **Breaking Changes**
  * ModuleParent hierarchy and getModuleParent() removed
  * Logging API and adapter model replaced; LogLevel-driven log_generic signature changed

* **Improvements**
  * Unified, simplified module registration across build targets
  * Tests updated to reflect new module lifecycle and global symbol resolution

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.

Refactor LVGL code into kernel module (#472)
* **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.
