📝 Walkthrough

Walkthrough

variables_clear is removed as a module-level alias in logfire/__init__.py and dropped from the __all__ export list, making it no longer part of the public API. The autouse config fixture in tests/conftest.py is updated to call logfire.DEFAULT_LOGFIRE_INSTANCE.variables_clear() directly, since the module-level shortcut no longer exists.
