Set options.debug = true if we can reliably detect that the app runs in a debug build #4123
Description
So users can easily spot errors during development, the SDK can automatically enable debug mode when it reliably detects it's running in a debug build. When doing so, the SDK must communicate this in the docs and with a log message when initializing the SDK. When the user explicitly sets the debug option to false, the SDK must disable the debug mode.
