Split monolithic copier.go (1077 lines) into focused modules: - copier.go: Core framework (95 lines) - copy_value.go: Copy functions and type handling (858 lines) - reflect.go: Reflection utilities (100 lines) - converter.go: Type converter (38 lines) - options.go: Configuration (renamed from optiongs.go) Bug fixes: - Fixed string to *string copying (empty strings now work) - Fixed *time.Time to *time.Time copying - Fixed nil slice handling - Fixed copyStructToSlice pointer element handling Tests: Fixed critical data copy issues. Remaining method-mapping features require additional implementation.
