- PvP cooldown (optional, default off): turning PvP off no longer goes safe instantly -
instead a delay starts (cooldown.seconds, default 300) during which the player stays
attackable, then PvP turns off automatically. Action-bar reminders each minute, a chat
message when it ends, survives relog. While on it REPLACES the combat lock. Turn on
with cooldown.enabled.

- Combat-log punishment (optional, default off): a player who logs out while PvP is
effectively active (PvP on, including a running cooldown, or still combat-tagged) is
killed at the logout spot so they drop everything. Respects the keepInventory gamerule.
Turn on with combat-log.enabled.

- PvE loot bonus (optional, default off): players whose PvP is active get extra drops
from mobs they killed themselves (Risk = Reward). Three mob groups (hostile / neutral /
passive), each with its own switch and a 'percent' that may exceed 100. Per-mob overrides
in mobs.yml can set percent, custom item drops, and a money reward (money needs Vault and
loot-bonus.money.enabled). Master switch: loot-bonus.enabled.

- Vault is now an optional soft-dependency, used only for the loot-bonus money payout.
