I built this locally and I did not get a `bin/lldb-dap` only `lldb-vscde` as before, but it was an existing build folder. So if your clean build is correct you can ignore that part.

I followed the install instructions and got the "LLDB VSCode" extension with type "llda-dap" as expected (symlinking lldb-vscode instead).

Find in files also shows some more references to `lldb-vscode` that should be checked and/or changed.
