View full Jira issue details using `jirac`. Steps: 1. Check that `jirac` is available by running `jirac --version`.

Show the output clearly and use it to answer follow-up questions. Examples: - "view PROJ-123" → `jirac issue view PROJ-123` - "show me the details of PROJ-456" → `jirac issue view PROJ-456`
