Add MCP server management commands to Agent 365 CLI

[sellakumaran]

Introduced the develop-mcp command for managing MCP servers in Dataverse environments. Added subcommands for listing environments and servers, publishing, unpublishing, approving, and blocking MCP servers. All commands support --dry-run and --config options.

Updated README.md and DEVELOPER.md with examples and usage details for the new commands. Refactored the CLI codebase to include a new DevelopMcpCommand class and models for environments and servers. Implemented Agent365ToolingService for API interactions with detailed logging and error handling.

Enhanced configuration and logging in install-cli.ps1. Added regression and unit tests to ensure Azure CLI-style parameters, dry-run functionality, and consistent option patterns. Introduced JsonDeserializationHelper for handling double-serialized JSON responses. Updated constants and utilities for streamlined configuration.

Improved developer experience with better error handling and documentation. Ensured compliance with Azure CLI patterns and added comprehensive logging for debugging and audit trails.

Agent 365 CLI installed successfully. Run 'a365 --help' to verify installation.

Pull Request Overview

This PR introduces comprehensive MCP (Model Context Protocol) server management capabilities to the Agent 365 CLI. The implementation adds a new develop-mcp command with six subcommands for managing MCP servers in Dataverse environments, following Azure CLI patterns with named options, dry-run support, and interactive prompts.

Key Changes:

• Added DevelopMcpCommand with subcommands: list-environments, list-servers, publish, unpublish, approve, and block
• Implemented Agent365ToolingService for API interactions with authentication, logging, and error handling
• Created model classes for Dataverse environments and MCP servers with JSON serialization support
