// Transcript: fetch the verbatim transcript (逐字稿 / 语音转写原文) of MY most
// recent minutes (听记) in one step.
//
// Steps:
//  1. list my minutes via list_by_keyword_and_time_range (belongingConditionId
//     = "created"), optionally filtered by --keyword;
//  2. pick the newest entry (largest create time, falling back to the first
//     item) and read its taskUuid — reusing latestMinutesTaskUUID;
//  3. print that minute's verbatim transcript via get_minutes_transcription
//     (taskUuid + direction, mirroring helpers.minutesGetTranscriptionCmd).
//
// If the list is empty it reports "暂无妙记" instead of failing obscurely.
//

	Intent: "当你想直接读回自己最近一次会议听记的逐字稿（完整语音转写原文），又不想先翻列表、复制 taskUuid 再单独查转写时使用；" +
		"内部先列出你创建的听记（可用 --keyword 缩小范围），自动挑出最新的一条，再拉取它的逐字记录（每条含发言人、文本、时间戳）。" +
		"可用 --direction 控制排序：0=正序（时间递增，默认），1=倒序。这是只读操作，不会修改任何听记；" +
		"若你名下没有任何听记则提示「暂无妙记」。",
