[Idea]: Mv import auto-complete improvement

[marcbal]

Describe the feature

I’m using the new Paper dimension directory structure to properly organise my worlds on an internal server (build projects, templates for mini-game worlds, ...). Since Minecraft keys supports / in the value part (after the :), I can then have dimension keys that looks like pandacube:lobby/v3.

Multiverse-Core already manage to import and handle such worlds, but it looks like the auto-completion of /mv import only find dimensions that are not in sub-folders, only the one directly in the namespace folder.

My feature request is about improving the auto-completion to find dimensions inside sub-folders too.

How is the feature useful to all Multiverse users?

I may not be the only one using sub directories to organize my world/dimensions folders

Agreements

• I have searched for and ensured there isn't already an open issue regarding this.

I had a thought about this before, but the main concern is the possibility of excessive file traversal if it do a nested lookup for valid world folders, which can potentially traversal huge data/region folders. One potential solution i see is to limit to only 1/2 depth, never traverse into folders that are already worlds and have some hard cap e.g. max 1k files. This should be enough for what most people use folders for i think.

ohyea can see that now is more viable as well for 26.1+ with an isolated dimensions folder, because prior world folders were mixed in with server folders, and it would have to look through all the folders on the server which was what i didnt want to do.
