+/**
+ * 建立議題。
+ *
+ * 兩個刻意的限制：
+ *   - 標籤只能指定 repo 上已經存在的，指到不存在的就中止。本工具不建立標籤。
+ *   - 以標題查重，同名議題已存在就回傳既有那一顆，讓中斷後重跑不產生重複議題。
+ *
+ * `--dry-run` 不寫入，但會讀：要讓預覽忠實反映將送出的請求，就得先把標籤名稱換成 id、
+ * 也得先查過重——否則預覽看起來會建一顆議題，實跑卻是 no-op，或反過來實跑才爆標籤錯字。
+ *
+ * 用法：
+ *   node scripts/issue-create.js --repo owner/name --title <標題> --body-file <路徑>
+ *                                [--labels a,b] [--host <網址>] [--dry-run]
