v1.0.2: Fix Compiler Warnings

Changes

Fixed

• Fixed duplicate import Foundation statement in MerkleTree.swift
• Fixed compiler warnings in BuilderTests.swift about unused mutable variables
  • Changed var newBuilder = self pattern to direct self mutation
  • Since BaseBuilder is a class (reference type), we can mutate self directly

Testing

• All 67 unit tests passing
• Zero compiler warnings
• Clean build with no errors or warnings

Impact

This release improves code quality by eliminating compiler warnings while maintaining full test coverage and functionality.
