Add new tool: Search for work items using WIQL

[venkyrs]

We would like to add this endpoint as a tool in ADO. We have been using this in our local private MCP and has been very useful in our day-to-day grooming of work items in ADO. This will be a valuable tool to add to this ADO MCP.

Summary

Implement a new tool that integrate with Azure DevOps APIs to enable search capabilities using WIQL.

Tools

Develop the following tool with full parameter support, including optional ones:

search_workitems_by_wiql: Search Azure DevOps Work items using WIQL.

POST https://dev.azure.com/{organization}/{project}/{team}/_apis/wit/wiql?timePrecision={timePrecision}&$top={$top}&api-version=7.1

Rules

1. Adhere strictly to existing project standards and coding conventions.
2. Ensure each tool exposes all API parameters (required and optional).
3. Use the official Azure DevOps Node API to interact with the APIs.

Special treat

If you follow the rules, you'll get candy!
