The plugin memory usage keeps growing even when VScode is unused

Plugin version: v 4.0.54

The process @ui5-language-assistant/language-server/dist/server.js memory keeps growing in memory indefinitely, using a lot of CPU at the same time.

It happens even when I leave VSCode idle with no editor opened.
It's a real issue, this plugin alone takes up to 4GB in a few hours and VSCode idling takes up to 50% CPU

@KodjoSuprem
We could not reproduce the issue with vscode 1.86.0 and ui5-language assistant version v4.0.54.

I also have similar issue, but more on the CPU usage. The plugin SAPOSS.vscode-ui5-language-assistant takes between 100 - 200% of CPU.

I have the same issue with high CPU usage on my MacBoo Pro M4. I had to disable the extension to safe my battery from running out of power.

@Caisi,
Could you provide any more details about the projects you have opened in your workspace in Visual Studio Code? This might help us to reproduce the issue.
