Use deployed package chain for attribute queries to exclude undeployed attributes.
Group primitive attributes under their parent variable node (merged Variable+Object).
Add is_historized and is_alarm detection via HistoryExtension/AlarmExtension primitives.
Implement OPC UA HistoryRead backed by Wonderware Historian Runtime database.
Implement AlarmConditionState nodes driven by InAlarm with condition refresh support.
Add historyread and alarms CLI commands for testing.

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
