参数:

• channel: 频道用户名（必填）。
• limit: 返回条数（1-100，默认 20；>20 时服务端会自动向更老方向翻页累积）。
• before: 翻页游标 —— 取「更老」的消息，回传上一页响应里的 data.pagination.before_cursor。
• after: 翻页游标 —— 取「更新」的消息，回传上一页响应里的 data.pagination.after_cursor。

返回:

• channel_info（结构同 fetch_channel_info）、messages 数组、pagination 游标对象。
• 媒体直链（cdn4.telesco.pe）带签名且会过期，请尽快下载/转存。

[English]

Purpose:

• Fetch a public channel's recent posts (text, photos, videos, forwards, replies, link previews, reactions, views, time).

Parameters:

• channel: Channel username (required).
• limit: Number of posts (1-100, default 20; when >20 the server automatically pages toward older posts).
• before: Pagination cursor — fetch older posts, pass data.pagination.before_cursor from the previous page.
• after: Pagination cursor — fetch newer posts, pass data.pagination.after_cursor from the previous page.

Return:

• channel_info (same structure as fetch_channel_info), messages array and a pagination cursor object.
• Media direct links (cdn4.telesco.pe) are signed and expire — download / re-host them promptly.
