Replaces the single LOLSCHEDULE_CHAT_ID env var with a KV-backed
subscriber list. New commands /lolschedule_subscribe and
/lolschedule_unsubscribe let each chat opt in/out. The cron now fans
out to every subscriber via Promise.allSettled so one blocked chat
cannot break the others.
- Commands renamed: /lol_today → /lolschedule_today, /lol_week → /lolschedule_week.
- Today view groups events under a league header per section.
- Week view nests leagues under each ICT day.
- LEAGUE_ORDER gives tier-1 tournaments priority (Worlds / MSI / First Stand,
then LCK / LPL / LEC / LCS, etc).
- New cron "0 1 * * *" (08:00 ICT) pushes today's major-league schedule to
LOLSCHEDULE_CHAT_ID via the Telegram Bot API. Skips cleanly when chat id
or token is missing, or when today has no major-league matches.
