feat(build): add build log and backup files for improved debugging and resource management

- Introduced a new build log file to capture detailed build process information, aiding in troubleshooting and performance analysis.
- Created backup files for critical source files to ensure recovery options during development.
- Updated various source files to enhance memory safety and resource management, including adjustments to cvar handling and filesystem operations.
- Addressed warnings and errors in the codebase to improve overall stability and maintainability.
