Worked on modernizing the build environment for the MaaAssistantArknights repository by updating the macOS deployment target to version 13.4 using CMake. This change focused on enabling compatibility with to_chars-based functionality, ensuring that the project could leverage newer macOS toolchains and libraries. The update reduced the risk of future build failures and streamlined the developer workflow by aligning the build configuration with current standards. The work involved build system configuration and CMake scripting, laying a foundation for future enhancements that depend on to_chars support. No bugs were addressed during this period, with efforts concentrated on proactive infrastructure improvements.
