Reproduce the panic from callHierarchy/outgoingCalls at ripgrep's crates/core/messages.rs line 124 using the reported rust-analyzer setup. Start with handlers::request::handle_call_hierarchy_outgoing, then inspect lsp::to_proto::range and line_index::LineIndex::line_col. Done means the request no longer panics and returns a valid outgoing-call result.
