Pin multi-stark to c683c69 for hybrid CPU/CUDA scheduling and update the Rust toolchain to 1.98.1. Use the merged Blake3.lean revision 78f5bc4 in both Lake and Nix so the Rust static libraries share the same toolchain. Refresh Cargo.lock, the Lake manifest, the Nix Rust manifest checksum, and the Blake3.lean flake lock entry. Validated on x86_64-linux with nix flake check (Clippy, 1,304 Rust tests, and the Lean suite) and a release workspace/all-targets CUDA cargo check through the Nix CUDA shell.

Point Aiur at the multi-stark revision that balances large mixed-height commitments across host CPUs and CUDA according to device capacity. The backend carries hybrid placement through lookup, quotient, openings, and FRI while preserving the existing Goldilocks/BLAKE3 protocol and CPU verification path.
No Ix source or build configuration changes are required: the existing opt-in cuda feature chain selects the new backend, while default builds remain CUDA-independent. Cargo.lock records the matching dependency graph.
Validated with release clippy across the non-CUDA CI feature set, a release all-targets CUDA check, and IX_CUDA=1 lake build bench-typecheck, including the final Rust static-library link.
