* **New Features** * Centralized module management with global symbol resolution * Level-aware logging with colored prefixes and millisecond timestamps * **Breaking Changes** * ModuleParent hierarchy and getModuleParent() removed * Logging API and adapter model replaced; LogLevel-driven log_generic signature changed * **Improvements** * Unified, simplified module registration across build targets * Tests updated to reflect new module lifecycle and global symbol resolution
