Magma Lexer String Literal Tokenization
In the Pygments Magma lexer, string literals are handled by transitioning into a dedicated 'string' state upon encountering a double quote ". Inside this state, regular string characters are matched by r'[^\\"]+' yielding String, escaped characters are matched by r'\\.' yielding String.Escape, and a terminating double quote r'"' pops the state with #pop.
