- Create math/big for big.Int utilities (HexOrDecimal256, U256, parsing) - Create math/safe for overflow-safe arithmetic (SafeAdd, SafeMul, etc.) - Move averager files to root package level - Add re-exports in root package for backwards compatibility - Update README with new package structure documentation - Remove old math/meter directory (consolidated elsewhere) - Remove redundant math/ subdirectory structure
