Azure DevOps support for /delegate command

[armaansood]

Describe the feature or problem you'd like to solve

The /delegate command currently only works with GitHub repositories. I work primarily with Azure DevOps (ADO) repositories and cannot use this feature. Many enterprise developers use ADO, so this limits the reach of one of the CLI's most powerful features.

Proposed solution

Extend /delegate to support Azure DevOps repositories, leveraging the existing ADO tooling already built into the CLI (ado-repo_create_pull_request, ado-repo_update_pull_request, etc.).
Since Microsoft owns both GitHub and ADO, this integration would be a natural fit.

Benefits:

 - Same seamless delegated workflow for ADO users
 - Broader enterprise adoption
 - Leverages existing ADO MCP tools already in the CLI

Example prompts or workflows

• /delegate fix the bug in UserService.cs → Creates a PR in my ADO repo with the fix
  • /delegate add unit tests for the new API endpoint → Delegates test creation to remote agent, opens ADO PR
  • /delegate refactor this module to use dependency injection → Complex refactoring delegated and PR created in ADO
  • /delegate implement the feature described in work item #12345 → Integrates with ADO work items
  • /delegate update documentation for the new release → Documentation changes delegated with ADO PR

Additional context

The CLI already has robust ADO integration via MCP tools (I've successfully used ado-repo_create_pull_request, ado-repo_update_pull_request, etc.). The building blocks exist - it's a
matter of wiring /delegate to use these tools when the remote is an ADO repository instead of GitHub.
