NPE: getHax() is null

[MineYuanlu]

Pre-reporting checklist

• I have searched existing issues and didn't find any previous reports of this bug.
• This bug still happens in the latest version of Wurst. I've made sure my installation is up to date.
• I have tried removing all other mods and the bug still happens.

Description

java.lang.NullPointerException: Cannot read field "nameProtectHack" because the return value of "net.wurstclient.WurstClient.getHax()" is null
    at net.minecraft.util.StringDecomposer.modify$djb000$wurst$adjustText(StringDecomposer.java:528)

some mod (like EffectInsights and EnchantmentInsights) parse text components (via ComponentHelper.getAsString) on ​​initialization.
The parsing process will traverse the component styles and call StringDecomposer.iterateFormatted, which will trigger the adjustText method injected by Wurst, resulting in a null pointer exception.

fix

src/main/java/net/wurstclient/mixin/StringDecomposerMixin.java

	private static String adjustText(String text)
	{
		HackList hax = WurstClient.INSTANCE.getHax();
		if (hax == null)
			return text;

		return hax.nameProtectHack.protect(text);
	}

Repro steps

1. add mod Wurst 7.54 and Enchantment Insights 26.1.0
2. launch Minecraft

Wurst Client version

7.54

Minecraft version

26.1.2
