README

• server runtime stats helpers

Package layout

• lib/JsonRpc/ - transport, request/response objects, client/server session handling
• lib/Core/Dispatcher/ - method/event dispatch strategies
• lib/Core/Middleware/ - request pipeline middleware
• lib/Handler/ - built-in protocol handlers
• tests/Integration/ - integration tests for pipeline, middleware, dispatcher, and handlers
