I may be lacking context (haven't interacted with leanSig in a while), but haven't they reverted back to Poseidon1 after the recent findings against Poseidon2? |

WIP LeanSig implementation for Miden.
Unlike the current EF LeanSig instantiation, this uses the Goldilocks field and Miden-native Poseidon2 rather than KoalaBear Poseidon1, so it is not wire-compatible. LeanSig itself is not tied to Poseidon1, and BLAKE3 is also being considered.
Tracking issue: #3439
