In `@crates/stdlib/src/gc.rs`:
- Around line 5-13: The module attribute definition for gc.garbage uses
#[pyattr] which recreates an empty list on each access; change the attribute to
#[pyattr(once)] on the garbage function so the created list is stored/persistent
across accesses (matching CPython semantics) — update the attribute macro on the
garbage function (fn garbage(vm: &VirtualMachine) -> PyObjectRef) to
#[pyattr(once)] so gc.garbage returns the same mutable list instance each time.

| /// A list of objects which the collector found to be unreachable | ||
| /// but could not be freed. RustPython doesn't have cyclic GC, | ||
| /// so this is always an empty list. | ||

Use #[pyattr(once)] to make gc.garbage persistent across accesses.
The #[pyattr] macro without (once) recomputes the value on each attribute access, creating a new empty list every time. This breaks compatibility with CPython, where gc.garbage is a mutable list that persists between reads. Code that modifies it (e.g., gc.garbage.clear() in tests) will lose those changes. Use #[pyattr(once)] instead to cache the result in a static cell, matching the pattern used elsewhere in RustPython for persistent module attributes.
