feat: Enhance GitHub issue handling with assignees and linked PRs

- Added support for assignees in GitHub issue data structure.
- Implemented fetching of linked pull requests for open issues using the GitHub GraphQL API.
- Updated UI to display assignees and linked PRs for selected issues.
- Adjusted issue listing commands to include assignees in the fetched data.
