Fix Essentia Build CI Failure
Problem: Essentia build fails due to C++ standard mismatch (C++11 vs C++14)
Root Cause: Eigen 5.0.1 requires C++14, but Essentia's WAF build system defaults to C++11
Changes Made:

Original prompt
✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.
Note
In the GitHub Actions macOS workflow, configure Essentia with C++14/libc++ by setting CXXFLAGS during waf configure to resolve Eigen compatibility.
