Kani contracts and harnesses for verify-rust-std challenge. Fixes rust-lang#83
Apply rust-lang rustfmt.toml (style_edition 2024, use_small_heuristics=Max) so upstream_test format check passes. Same as ./scripts/check_rustc.sh --bless.
Add kani::modifies on atomic store/RMW contracts and wrappers. Proofs use live stack objects instead of wrapping_add pointers, which lose provenance and fail CBMC's assignable check. Fixes rust-lang#83
