Detailed Description

Session that routes G4cout and G4cerr through the Framework logger.

This session intercepts all Geant4 output and routes it through the Framework's logging system with the logger name "Geant4". Messages are parsed to determine appropriate log levels:

• G4cout with "WARNING" -> warn
• G4cout with "ERROR" -> error
• G4cout with verbose tracking info -> trace
• G4cout default -> debug
• G4cerr with "ERROR" or "FATAL" -> error
• G4cerr default -> warn
