Add runtime address space rebuild integration tests
Tests verify nodes can be added/removed from the OPC UA server at runtime by mutating FakeGalaxyRepository and triggering a rebuild. Uses real OPC UA client sessions to browse, subscribe, and observe changes. Tests cover: - Browse initial hierarchy via OPC UA client - Add object at runtime → new node appears on browse - Remove object → node disappears from browse - Subscribe to node, then remove it → publishes Bad quality - Surviving nodes still browsable after partial rebuild - Add/remove individual attributes at runtime Infrastructure: - OpcUaTestClient helper for programmatic OPC UA client connections - OpcUaServerFixture updated with GalaxyRepository/MxProxy accessors - OpcUaService.TriggerRebuild() exposed for test-driven rebuilds - Namespace index resolved dynamically via session namespace table Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
