Extract Microsoft.Mcp.Core types from AzureMcp.Core

[Copilot]

This PR extracts Azure-agnostic classes from AzureMcp.Core into a new Microsoft.Mcp.Core library, preparing for the multi-server microsoft/mcp migration as outlined in the architecture diagram:

Azure.Cli ──────────────────────► Azure.Mcp.Core ─────► Microsoft.Mcp.Core
     │                                    │                      │
     └─► Areas (Storage, KeyVault, etc.) ─┘              ◄──────┘
                                                         (Generic MCP)

Key Changes

Created Microsoft.Mcp.Core Library

A new Azure-agnostic MCP library containing:

• MCP Runtime & Server Infrastructure: Core MCP server functionality, hosting, and protocol handling
• Tool Loading & Discovery: Plugin-style tool discovery and loading mechanisms
• Base Command Infrastructure: Generic command system, factories, and processing
• Generic Services: HTTP client, process execution, time, and base telemetry services
• Models & Helpers: Base models, validation, and utility functions

Refactored Azure.Mcp.Core Library

Renamed from AzureMcp.Core and now contains only Azure-specific functionality:

• Azure Commands: SubscriptionCommand, GlobalCommand with Azure authentication
• Azure Configuration: AzureMcpServerConfiguration and Azure-specific options
• Azure Services: Authentication, resource management, caching, and Azure telemetry
• Azure Models: AuthMethod, AzureCredentials, ETag, ResourceGroupInfo
• Azure Extensions: OpenTelemetry integration and Azure-specific service registration

Architectural Benefits

• Clean Separation: Azure-specific code is isolated from generic MCP functionality
• Extensibility: Base classes in Microsoft.Mcp.Core can be extended for other platforms (Fabric, etc.)
• Reusability: Generic MCP infrastructure can be shared across multiple server implementations
• Maintainability: Clear boundaries between platform-specific and generic code

Technical Implementation

• Virtual Methods: Created extension points in ServiceStartCommand for platform-specific overrides
• Public APIs: Made necessary interfaces public for cross-library access
• AOT Compatibility: Fixed JsonSerializer issues for native AOT compilation
• Package Management: Added Microsoft.Extensions.Http to central package management

The extraction successfully enables the multi-server architecture while maintaining all existing functionality through the Azure.Mcp.Core → Microsoft.Mcp.Core dependency chain.

Fixes #954.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
