Subject: [PATCH] Fix Boost.Bind deprecation warnings with version compatibility

Use conditional compilation to support both old and new Boost.Bind API:
- Boost >= 1.73.0: Use boost/bind/bind.hpp
- Boost < 1.73.0: Use boost/bind.hpp

This approach maintains backward compatibility while fixing deprecation
warnings in newer Boost versions.
