Rodin::Alert::Exception class

Exception class with formatted output capabilities.

A specialized exception class that extends both std::exception and the Alert messaging system. When raised, it outputs a formatted error message with red coloring and terminates the program.

The Exception class provides stream-like insertion operators for building detailed error messages with formatting capabilities.
