Hardcore Reset

No more "one death and it's over." **Hardcore Reset** turns death into a *world*
event instead of a *personal* one: when anyone dies, their death is cancelled,
a 5-second countdown plays out in chat, and then the entire world — Overworld,
Nether, and End — is thrown away and regenerated from a brand new seed. Every
player online, including whoever died, is teleported into the fresh world with
a clean inventory, XP, and advancements. Nobody is kicked, and nobody has to
leave and manually recreate the save.

## Features
- Any player death triggers a full world reset instead of a game over
- 5 second countdown broadcast in chat before the reset happens
- Overworld, Nether, and End are all regenerated together with a new random seed
- Every online player is teleported to the new spawn, healed, and has
  inventory/XP/advancements cleared
- No kicking, no manual save deletion — it all happens live while everyone
  stays connected
- Gamerules, difficulty, and clock settings carry over into the new world
