Subject: [PATCH] feat(loldle): reject duplicate guesses within a round
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prevents two players in a group from wasting a slot on the same champion —
re-guessing a previously tried champion replies with a hint and does not
consume a guess.
