Brandon Schneider 235be32ec9 feat(lean): prove BraidDiatFrame roundtrip + MMR.mountainList 
- Add BraidField.MMR.mountainList helper to convert MMR to List Mountain
  in decreasing-height order (unwrap cons structure)
- Fix BraidDiatFrame.encode: use UInt32.ofNat for stepCount (Nat → UInt32),
  fix DynamicCanal.IntNode → BraidField.IntNode reference
- Fix BraidDiatFrame.decode: use toNat for stepCount (UInt32 → Nat),
  remove List.ofFn (requires proof of in-bounds) with Fin-based loop
- Fix toMountain: replace List.ofFn with foldl over List.range
- Fix encode_decode_roundtrip: prove decode(encode(state,receipt,chir,n,residuals))
  recovers original state.mmr, chirality, n, and receipt fields when n valid
- Fix decode_encode_roundtrip: prove encode after decode recovers frame fields
- Change #eval example Chirality.positive → Chirality.right (correct variant)
