//! Live-applies a client configuration change without a server restart: pushed
//! runtime settings (currently `experimental.incrementalParsing`) update in
//! place, on-disk `panache.toml` config is re-read for every open document, and
//! the debounced settle re-publishes diagnostics over the fresh state.
