Port missing test coverage from the internal lazy imports test suite to cpython's test_lazy_import, covering behaviors not previously tested: - Dict operations with lazy values (copy, |, update, values/items) - from X import * resolution behavior with lazy imports - Submodule laziness (unused submodules stay lazy, side effects) - Attribute side effects (submodule imports don't overwrite parent attrs) - Module/variable name collisions (submodule vs variable ordering) - Deleted module reimport (sys.modules deletion and reimport) - Circular import resolution (lazy imports breaking circular deadlocks) - Custom __import__ via exec with lazy imports - Dict mutation during module loading - Runtime enable/disable of lazy imports via sys.set_lazy_imports() Adds supporting test data modules: metasyntactic package hierarchy, versioned package, module_same_name_var_order packages, circular_import_pkg, and cycle_with_load_global_pkg.
