Werewords Deluxe

Is a Werewolf-Mayor required to acknowledge if somebody guesses the Magic Word?

Technically, yes, they need to give that player the Correct token. However, it is well within the spirit of the game for a Werewolf-Mayor to "not hear" a guess if they can get away with it (for example, multiple people are talking at once, and they opt to respond to the other person).
