Pull request overview

This PR migrates the Azure Managed Lustre toolset to the attribute-based options design (where option registration/binding is derived from [Option] / [OptionContainer]), removing the legacy RegisterOptions/BindOptions + System.CommandLine option-definition pattern and updating tests accordingly.

Changes:

• Converted Managed Lustre commands to the newer SubscriptionCommand<TOptions, TResult> execution model with attribute-based option POCOs.
• Removed legacy option-definition and base-command infrastructure (ManagedLustreOptionDefinitions, BaseManagedLustreCommand, System.CommandLine dependency).
• Updated Managed Lustre unit tests to use the newer command test base classes and explicit Xunit usings.
