Add cross-platform OPC UA client stack: shared library, CLI tool, and Avalonia UI

Implements Client.Shared (IOpcUaClientService with connection lifecycle, failover, browse, read/write, subscriptions, alarms, history, redundancy), Client.CLI (8 CliFx commands mirroring tools/opcuacli-dotnet), and Client.UI (Avalonia desktop app with tree browser, read/write, subscriptions, alarms, and history tabs). All three target .NET 10 and are covered by 249 unit tests. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
