bulk-createlisted

Create multiple Jira issues in bulk 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. Build a JSON manifest array from the user's request. Each object supports: - `project` (required), `summary` (required) - `type` (default: "Task") - `assignee` (email or "me"), `priority`, `labels` (array), `components` (array) - `parent` (issue key), `fix_versions` (array), `description` (Markdown string) - `fields` (object of custom field IDs → values, e.g. `{"customfield_10016": 5}`) 3. Save the manifest to a temp file (e.g. `/tmp/issues.json`). 4. Run `jirac issue bulk-create --manifest /tmp/issues.json`. 5. Confirm each created issue key and summary. Manifest format: ```json [ { "project": "PROJ", "summary": "Issue title", "type": "Task", "assignee": "user@org.com", "priority": "High", "labels": ["backend"], "components": ["auth"], "parent": "PROJ-100", "fix_versions": ["v1.0"], "description": "Markdown description", "fields": { "customfield_10016": 5 } } ] ``` Examples: - "create 3 tasks in PROJ: setup DB, setup API, setup UI" → build manifest with 3 Task entries, run `jirac issue bulk-create --manifest /tmp/issues.json` - "buat bulk issue dari daftar ini" → build manifest from the list, run `jirac issue bulk-create --manifest /tmp/issues.json`
