This file is used exclusively for development, static analysis tools, and CI testing - it is not used during runtime compilation. When developing components that add new defines, they must be added to this file to ensure proper IDE support and static analysis coverage. The file includes feature flags, build configurations, and platform-specific defines that help static analyzers understand the complete codebase without needing to compile for specific platforms.
