RAM memory growing usage during run

Hi, I had this issue on this extension. It just started to grow and it became so big that my browser started crashing and then I observed that this extension is a problem.

@oxfrd Which process is using the RAM? We've received other reports of this which are caused by VS Code itself from some Copilot-related functionality. It would only be our bug if the cpptools or cpptools-srv process were using the memory, since our extension host process generally does not implement any functionality which could consume memory like this (even if disabling our extension may stop it from reproing, i.e. due to binary/database files that aren't created, etc.).
