Initial commit: Azure DevOps TUI client

A terminal-based user interface for browsing and managing Azure DevOps
work items. Features include:

- Browse work items with filtering by area, iteration, state, and type
- View work item details with markdown rendering
- Open work items in browser
- Create git branches from work items
- Update work item state
- Keyboard-driven navigation
