Regarding the testing. It looks like we have two ways of testing this:

1. Add clangd-specific protocol handlers that output useful stats(i.e. currently opened documents), use those in tests.
2. Add unit tests that emulate the protocol actions and run the checks in C++.

Option 1 seems preferable, we could probably use the 'workspace/executeCommand' for that.
