Handles init, initialize, initialized, didOpen, didChange, didClose, and generic request/notification forwarding. Includes per-connection doc tracking and cleanup on disconnect, plus graceful shutdown integration.

Locally this wasn't an issue because dist/ directories already existed from prior builds. Docker starts fresh with no dist/. Fix: COPY nx.json into all three Dockerfiles so nx can read targetDefaults.build.dependsOn and build packages in correct order.
