list-issueslisted

List Jira issues using `jirac`. Steps: 1. Check that `jirac` is available by running `jirac --version`. If it is missing, tell the user to install it with `cargo install jira-commands`. 2. Determine the query from the request: - project key - explicit JQL - otherwise use the default assigned-to-current-user behavior 3. Run `jirac issue list` with the right flags. 4. Present the results clearly. Notes: - `jirac issue list` without flags defaults to `assignee = currentUser()`. - `jirac issue list -p PROJ` limits to one project. - `jirac issue list --jql '<expression>'` gives full control. Examples: - "list my issues" → `jirac issue list` - "list issues in PROJ" → `jirac issue list -p PROJ` - "list open bugs in PROJ" → `jirac issue list --jql 'project = PROJ AND issuetype = Bug AND status != Done'`
