Register function environment variables

This extension is able to detect usage of undefined global variables:

However, setfenv is used on this function to define the missing variable, but at another point in the code that the parser can't detect. Is it possible to somehow tell the parser to ignore this diagnostic? Something like:

local block = function(_)
    -- env: {block, assert, error}
    block()
end

Then it would accept those values? I know you can define globals for the project, but this doesn't affect the entire project, only those functions, so it would be cool if you could define it somehow.

Alternatively, could we just disable the diagnostic?

local block = function(_)
    -- disable: undefined-global
    block()
end

I don't know if the parser supports reading comments like that, let me know if that won't work or if you have better ideas for it.

首先追蹤 parser 的未定義全域變數診斷，以及它如何讀取專案層級的全域定義。評估 issue 中提出的函式區域環境註解和停用診斷的註解，然後確認所選語法只會抑制或解決預期的函式範圍警告。
