[Feature Request] Multiple-project/Monorepo support

I work with a large monorepo that contains multiple Lua project roots. You can actually see the list of Lua projects here, as an example: https://github.com/SmartThingsCommunity/SmartThingsEdgeDrivers/tree/main/drivers/SmartThings

Loading this entire repo at once doesn't work well because of how the require paths are established via runtime.path. The primary issue is that it leads to ambiguous require resolution if two of the roots have files with the same name.

Obviously, one workaround is to use a multi-root workspace and only add the folders for the projects I currently care about, but that's tedious since I'd be adding and removing folders from the workspace constantly.

One idea that I had was being able to specify an "entrypoint" glob. The plugin could traverse up the directory tree looking for a file that matches the glob, and then use that as the root for all local requires. But that might not be a good "general" solution even though it works well for my use case.

首先检查 runtime.path 如何建立本地 require 根路径，以及当 repository 包含多个 Lua 项目根路径时其行为如何。issue 提出了 entrypoint glob 作为一种可能的方向，但没有指定首选设计或需要修改的文件。完成应意味着可以在没有歧义的 require 解析的情况下加载 monorepo。
