1. 更改导出的默认行为, 现在如果是作为库/包文件解析, 则无法在主代码库内导入(报错), 必须要显式声明---@export global才能导出
2. 新的路径占位符"${luarocks}"

Summary of Changes

Hello @xuhuanzy, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a more flexible and context-aware system for handling export visibility in Lua code analysis. By adding a Default export scope, the system can now apply nuanced visibility rules, especially for modules that do not explicitly declare their export behavior. Additionally, the changes enhance the parsing of export tags within return statements, allowing for a broader range of Lua expression types to be correctly analyzed, leading to more precise semantic understanding.

Highlights

• New Default Export Scope: Introduced a Default variant to the LuaExportScope enum, which will be used when no explicit export scope (like global or namespace) is specified for a module. This allows for configurable default behavior.
• Enhanced Export Tag Analysis: Improved the analyze_export function to correctly identify the owner of an export tag within LuaReturnStat. It now supports NameExpr, ClosureExpr, and TableExpr, providing more accurate semantic analysis for returned values.
• Refined Default Visibility Logic: Implemented a new check_default_export_visibility function. This function determines visibility for the new Default scope, treating modules identified as library files as not visible by default, while other files are considered visible.

Code Review

This pull request enhances the @export functionality by extending its support on return statements to include named variables and closure expressions, not just table expressions. It also introduces a new Default export scope, which intelligently adjusts module visibility based on whether it's part of a library, making modules in libraries non-visible by default unless explicitly exported. This is a thoughtful improvement for better visibility control. The changes are consistent and well-implemented across the board. I have one minor suggestion to improve code conciseness.
