This commit introduces a significant reorganization of the project structure to improve maintainability and clarity. Key changes include: - Adjusted the directory layout for a more logical module organization. - Removed unused crate dependencies, reducing the overall project size and potentially speeding up build times. - Updated import paths and configuration files to reflect the structural changes.
