feat(wordledaily): add the daily Wordle HTML5 game

/wordledaily sends a BotFather game card whose page plays one shared word
per day, changing at 07:00 ICT. The server checks guesses, saves each
player's board after every guess and keeps NYT-style stats. A win is
reported with setGameScore, and in a group one live results message shows
everyone's colour grids.

/wordledaily_subscribe and /wordledaily_unsubscribe opt a chat or topic in
to the 07:00 push: yesterday's recap, opening with the answer and the
group's win streak, then today's card.

The HTML5 game plumbing that noitu used is now shared in util/htmlgame, and
the wordle word list and scoring live in wordle/wordlist.
