OpenTelemetry ws Instrumentation

OpenTelemetry instrumentation for the `ws` WebSocket library, providing automatic tracing of socket lifecycle events: opens, closes, sends, and optionally messages. Current version 0.5.0 is stable, released monthly. Differentiates from manual instrumentation by patching the `ws` module transparently, supporting both client (`WebSocket`) and server (`ws.Server`) sides, and offering hooks for custom attributes. Requires `ws@^8.5.0` as a peer dependency and the OpenTelemetry Node SDK.
