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.

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

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.

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.

TactilityKernel improvements (#464)
* **New Features**
  * Thread API with lifecycle, priority, affinity and state monitoring
  * Timer subsystem: one-shot/periodic timers, reset, pending callbacks, expiry queries
  * Expanded I²C: register-level ops, bulk writes, presence checks, ESP32 integration and new config properties
  * GPIO controller: pin level and options APIs
  * Error utilities: new error code, error-to-string, timeout helper and common macros
  * Device construction helpers (construct+start)

* **Tests**
  * New unit tests for thread and timer behavior

* **Documentation**
  * Expanded coding style guide (files/folders, C conventions)

Moved and renamed files for consistent C code style (#463)
* **Documentation**
  * Added new C coding style guide detailing naming conventions for files, directories, macros, constants, variables, functions, and type definitions with illustrative examples.
  * Updated C++ coding style documentation with clarifications on C naming conventions and header directory organization patterns.

* **Refactor**
  * Updated header include paths throughout the codebase to use lowercase naming conventions consistently.
