Expected Behaviour

After generating documentation with --doc, I expected to have access to the all of the information available in the annotations that is presented or used by the language server.

Actual Behaviour

There were a few things that are missing or strange:

• @see annotations are absent.
• Access levels (@protected, @private, @package) are absent.
• Aliases that extend other aliases include the documentation of the alias that they extend, which makes it difficult to tell which documentation belongs to only the extended alias.
• The start and finish fields seem odd; they're very large numbers (e.g., 5490009, 5490021) that clearly don't refer to character ranges within the files. What are these numbers?

For the purpose of generating documentation, the first two problems seem significant—it would be difficult to filter out private fields and methods, for example.

Reproduction steps

1. Create a Lua file that uses access modifiers, @see, and an alias that extends another alias. I've provided a minimal example of such a file below.
2. Observe the missing data and oddities.

Additional Notes

Example for reproduction:

---@class C
---@field private z integer
local C = {}

---Base alias doc comment.
---@alias Base
---| 'A'
---| 'B'

---Extended alias doc comment.
---@alias Derived
---| Base
---| 'C'

---@protected
function C.x()
end

---@see C.x
function C.y()
end

No response

首先针对 issue 中的 Lua 复现运行 --doc 导出，并检查其输出如何表示 @see、访问修饰符、继承的别名文档以及 start/finish。跟踪文档导出的入口点，并将其输出与 language server 使用的注解信息进行比较。当导出的数据保留所请求的注解细节，并解释或修正范围值时，即表示完成。
