Boost 1.88 replaced Boost.Process with v2, breaking the v1 API. Boost 1.89 restores v1 compatibility via <boost/process/v1.hpp>. - Fail configuration if Boost 1.88 is detected - Define FAIRMQ_BOOST_PROCESS_V1_HEADER for Boost >= 1.89 - Use conditional includes to select v1.hpp or process.hpp - Add namespace aliases (bp, bp_this) for portable API access
