- Re-implemented the demo and interactive flashing functionality for the wled_config_tool from scratch based on the detailed specification in lessons_learned.md.
- Added a new WledClient::setLedsColor method to send the entire LED state in a single packet, preventing flickering.
- Fixed multiple build issues, including missing Qt module dependencies, deprecated function calls, and linker errors.
- Updated lessons_learned.md to document the code loss and recovery process, as well as the build fixes.
