Find libfaust.so on Linux, libfaust.dylib on macOS, libfaust.dll/faust.dll on Windows; join PATH with Path.PathSeparator; accept FaustLibraryPath or AQUASYNTH_FAUST_LIBRARY as an explicit library file. Platform default homes replace the unconditional C:\Program Files\Faust. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
