Fix hangman: lowercase 'r' key not registering as a guess

[ralyodio]

Problem

In hangman, pressing lowercase r did nothing during play. Shift+R worked, and r worked fine everywhere else in the arcade.

Root cause

hangman.Update() (plugins/arcade/hangman.go) bound "r" to "restart":

case "r":
    if h.dead {
        return newHangman(h.user, h.ctx), nil
    }
    return h, nil   // ← swallowed the keypress during active play

The return h, nil ate the r keypress whenever the game was still active, so r never reached the letter-guess logic. Shift+R produces key.String() == "R", which doesn't match case "r", so it fell through and worked — hence the asymmetry.

Fix

r now only restarts when the round is over (h.dead); during play it falls through to the normal guess handling. Added TestHangmanLowercaseRIsAGuess as a regression test.
