    Starts the ExDNA Language Server Protocol server over stdio.

    Configure your editor to run this command as an LSP server.
    It pushes code clone diagnostics alongside your primary Elixir
    LSP (e.g., Expert, ElixirLS).

    Requires the optional `gen_lsp` dependency:

        {:gen_lsp, "~> 0.11"}
