Previously getLogDir() only checked app.isReady(), which caused
development builds to write logs to the user data directory instead
of the local project logs/ folder. Now uses app.isPackaged to
correctly distinguish production from development environments.
Also adds comprehensive logging system documentation and a debug
utility for verifying Electron environment detection.
