Silently check today's NYT Wordle answer on startup

Queries the NYT wordle/v2 endpoint once per calendar day (cached via
~/.wordle_solver/state.json) and adds the word via the existing
/addword mechanism if it's missing from answers.txt. Fully silent in
every outcome; --no-nyt-check / --force-nyt-check control it from the
CLI.
