- Add minimal type stubs (.pyi) for v1/v2 compatibility without runtime changes - Move proxy imports to top-level for safe lazy loading (no PLC0415 needed) - Remove broad type ignores and implement targeted fixes: * Early returns for union-attr errors * -> Any annotations for dynamic helpers * cast() for v1/v2 bridging * TYPE_CHECKING for type-only imports - Fix Portuguese comments and ensure English-only codebase - Add I001 exception in pyproject.toml for conditional imports - Achieve 0 Ruff errors, 0 MyPy errors, all tests passing - Maintain full Pydantic v1/v2 compatibility with lazy loadingpull/14201/head
