Telegram 批量图文（album）发送：用 sendMediaGroup 降低多条消息噪音
问题/场景：自动化任务一次输出多张图片时，逐条发送会刷屏且上下文割裂。前置：Telegram 渠道可用，版本包含 media-group 能力。实施步骤：按批次组织媒体、设置首条 caption、统一发送并回执校验。关键命令/配置：message send 支持媒体分组（以实际版本为准）。验证：用户端显示为单个相册消息。风险：不同媒体类型混发和大小限制需要额外测试。来源：GitHub PR。

Prerequisites
- Telegram bot/channel is connected and has permission to send media.
- Your OpenClaw version includes or is upgraded to PR #21309 behavior.
Steps
- Prepare 2-10 media items for one logical update and order them before send.
- Put shared context in the first item caption; keep others caption-empty unless necessary.
- Send as one media group request instead of multiple single-message sends.
- Inspect Telegram client rendering and fallback to chunked sends if group delivery fails.
Commands
openclaw gateway statusopenclaw gateway restart# message tool: use one grouped media payload（按当前版本参数验证）Verify
Recipients see one album-style message with ordered media and correct lead caption.
Caveats
- Telegram album constraints (count/type/size) still apply and can reject oversized batches.
- Exact OpenClaw message-tool parameters for media group should be confirmed against current docs（需验证）.
