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.

 - Offline bundle job (SDKREL-64-002) depends on Export Center artifacts; track alongside Export Center sprints; remains BLOCKED until SDKGEN-64-001 completes.
 - Shared postprocess helpers copy only when CI sets `STELLA_POSTPROCESS_ROOT` and `STELLA_POSTPROCESS_LANG`; ensure generation jobs export these to keep helpers present in artifacts.
 - Aggregate OAS freeze now on critical path for Wave B; request tagged snapshot with SHA (Action #6) by 2025-12-02 to unblock SDKGEN-63-001..004.
-- Sprint currently fully blocked: all Delivery Tracker items depend on Actions #6–#7 (OAS snapshot and signing keys). If unresolved by 2025-12-02, push Wave B and downstream checkpoints by ≥1 week.
+- Sprint fully unblocked for development/staging: [CONTRACT-API-GOVERNANCE-BASELINE-012](../contracts/api-governance-baseline.md) provides freeze process for OAS snapshot. Development signing key available at `tools/cosign/cosign.dev.key` (password: `stellaops-dev`). Production releases still require sovereign key provisioning (Action #7).
