Optional global prefix for EssentialsX command messages #6391
Description
Feature description
Add an optional configuration setting that allows server owners to define
a global prefix which is automatically prepended to all messages sent by
EssentialsX commands.
The prefix applies only to messages generated by EssentialsX itself
(e.g. /warp, /spawn, /clear, permission errors) and does not affect
player chat, AsyncChat events or other plugins.
The feature is disabled by default (empty prefix) and does not require
any changes to messages.yml.
How the feature is useful
This makes it much easier to visually distinguish system messages coming
from EssentialsX commands from normal player chat or other plugins.
It improves clarity on larger servers, helps prevent fake system messages,
and avoids the need to manually edit every entry in messages.yml, which
is difficult to maintain and breaks translations.
