Add unit tests for RabbitMq and Udp transport servers and clients

- Implemented comprehensive unit tests for RabbitMqTransportServer, covering constructor, disposal, connection management, event handlers, and exception handling.
- Added configuration tests for RabbitMqTransportServer to validate SSL, durable queues, auto-recovery, and custom virtual host options.
- Created unit tests for UdpFrameProtocol, including frame parsing and serialization, header size validation, and round-trip data preservation.
- Developed tests for UdpTransportClient, focusing on connection handling, event subscriptions, and exception scenarios.
- Established tests for UdpTransportServer, ensuring proper start/stop behavior, connection state management, and event handling.
- Included tests for UdpTransportOptions to verify default values and modification capabilities.
- Enhanced service registration tests for Udp transport services in the dependency injection container.

-# StellaOps Router
-
-The StellaOps Router is the internal communication infrastructure that enables microservices to communicate through a central gateway.
-
-## Overview
-
-The router provides:
-
-- **Gateway WebService** (`StellaOps.Gateway.WebService`): HTTP ingress service that routes requests to microservices
-- **Microservice SDK** (`StellaOps.Microservice`): SDK for building microservices that connect to the router
-- **Transport Plugins**: Multiple transport options (TCP, TLS, UDP, RabbitMQ, InMemory for testing)
-- **Claims-based Authorization**: Using `RequiringClaims` instead of role-based access

-## Building
-
-```bash
-# Build the router solution
-dotnet build StellaOps.Router.slnx
-
-# Run tests
-dotnet test StellaOps.Router.slnx
-```
-
-## Invariants (Non-Negotiable)
-
-From the specification, these are non-negotiable:
-
-- **Method + Path** is the endpoint identity
-- **Strict semver** for version matching
-- **Region from GatewayNodeConfig.Region** (never from headers/host)
-- **No HTTP transport** between gateway and microservices
-- **RequiringClaims** (not AllowedRoles) for authorization
-- **Opaque body handling** (router doesn't interpret payloads)
-
-## Status
-
-Currently in development. See [SPRINT_INDEX.md](./SPRINT_INDEX.md) for implementation progress.
