"Unhandled Operation" Error during script compile is only logged but not thrown otherwise signalled

I was testing hou+ using the standalone compiler, and noticed two errors were output while compiling `&opening.txt`.

```c#
void OpeningLaunch()
{
if (GetGlobalFlag(GVideoOpening) >= 3) {
PlayOriginMovie();
}
}

void OpeningStory()
{
if (GetGlobalFlag(GVideoOpening) >= 2) {
SetGlobalFlag(GVideoOpening, 3);
PlayOriginMovie();
}
}

void PlayOriginMovie()
{
if (GetGlobalFlag(GArtStyle) == 2) {
// Play OG video if using OG artstyle
PlayVideo("video/mv13-pc.mp4", 1920, 1080);
} else {
// Otherwise play console art style
PlayVideo("video/mv13-cs.mp4", 1920, 1080);
}
}
```

The error is that `PlayOriginMovie();` should actually be `CallSection("PlayOriginMovie");`

I'm not sure if this works anyway, even without the CallSection, as the movie does seem to play.

But I was wondering how we've been running CI/building the scripts without noticing this error. I then checked where the error was raised:

```C#
public void ParseOperation(ITree tree)
{
name = tree.GetChild(0).Text;
line = tree.Line;
BGIParameters param = (tree.ChildCount <= 1) ? new BGIParameters() : new BGIParameters(tree.GetChild(1));
if (paramLookup.ContainsKey(name))
{
OutputCmd(name, param);
return;
}
Debug.LogError("Unhandled Operation " + name);
CmdOpNull();
}
```

It looks like the error is just printed out, but there is no signalling during compile that an error occurred, so the compiler thinks everything is OK.

----

Will need to check whether this was done deliberately (as the script seems to work anyway under this condition).

But personally, since this only happens if there is a genuine error, I would want to throw an exception and tell the developer to fix the script (since it should usually be an easy fix).

----

Also check if this applies to previous chapters (apply this fix to the `mod` branch)

查看编译器代码中记录“Unhandled Operation”错误的ParseOperation方法。问题在于将Debug.LogError更改为抛出异常或以其他方式发出编译失败信号。检查此模式是否存在于其他章节（mod分支）中。验证脚本在出现错误后是否仍能工作，因为用户指出电影似乎可以播放。
