Added

• New notifications.yml config file consolidating all notification settings (inbox, member join, economy tax, EzCountdown).
• EzCountdown relation announcements now fall back to a server-wide chat broadcast when EzCountdown is absent or disabled in config.

Changed

• EzCountdown integration is now fully optional: relation announcements are delivered via chat by default and only use EzCountdown when the plugin is present and notifications.ezcountdown.enabled is true.
• Notification settings moved from config.yml to notifications.yml: notify-members (economy tax) and all integrations.ezcountdown.* keys.
