Implement work iteration commands and DTOs for Azure DevOps

[danhellem]

This pull request refactors and modularizes the implementation of Azure DevOps work tools, particularly for creating/assigning iterations and updating team capacity. The main changes include extracting DTO schemas to a dedicated file, introducing a command-based architecture for tool actions, and updating the test and configuration logic to match the new structure.

Refactoring and modularization of work tools:

• Extracted Zod schemas and TypeScript types for work iteration and capacity write actions into a new file, work.dto.ts, ensuring type safety and single-source-of-truth for input validation and documentation.
• Replaced inline tool handler logic in work.ts with a command-based architecture. Each action (e.g., create/assign iteration, update capacity) is implemented as a separate command object, improving maintainability and testability. [1] [2]
• Updated the configureWorkTools function to inject the new user agent provider dependency and to use the new command dispatching mechanism for tool registration.

Configuration and test updates:

• Added a Jest moduleNameMapper entry for the new work.dto.ts file to ensure tests resolve imports correctly.
• Updated tests to expect new error messages for unknown actions, reflecting the improved error handling in the new architecture. [1] [2]
