0.3.0

• Removes the admin-only restriction from the F8 mist/gamma panel and mist shortcut.
• Converts visibility settings into per-player local preferences. Apply saves only that player's config.
• Removes server authorization, settings broadcasts, handshakes and remote settings overrides.
• Migrates existing locally saved values from Server to Personal without overwriting an existing Personal preference.
• Retains the wooden inventory-style panel, readable labels, gamma behavior, wisp ranges and shortcuts.
• Dedicated servers do not register visual or settings-sync hooks.
• Offline validation passed; live non-admin and multiplayer visual testing remains required.
