* **New Features** * Added native display support for ST7796, ILI9341, and ST7789 panels across supported boards. * Added FT5x06 and FT6x36 touchscreen support. * Generic PWM driver * ESP32 PWM driver * Generic RGB LED driver * RGB PWM LED driver * RGB GPIO LED driver * Implementation of RGB LED for various boards * **Improvements** * Updated board hardware descriptions to use explicit display/touch/backlight device-tree bindings and disabled deprecated HAL usage. * Improved display and touch-driver cleanup to prevent stale resources and improve shutdown reliability. * Pinned esp-hosted library to a fixed version * **Deletions** * Obsolete placeholder display * Legacy ILI9488 support. * ESP32-specific LEDC PWM implementation
