Replaces the wordle stub with a full implementation mirroring the loldle
module layout: compare/lookup/daily/render/state/handlers/index split,
per-subject KV state, standard 6 guesses, two-pass duplicate-letter
marking.
Commands: /wordle, /wordle_new, /wordle_giveup, /wordle_stats.
Word list (14,855 entries) sourced from dracos's gist
(https://gist.github.com/dracos/dd0668f281e685bad51479e5acaadb93) and
bundled via scripts/build-wordle-data.js. Credits in module README and
generated file headers.
Dispatcher test updated for the new command count (12 → 13).
