List a channel's community/Posts feed (text, publish time, like count text, and attachments — image, multi-image, video, playlist, or poll), paginated.

First request: provide channel (@handle, URL, or UC... ID). Subsequent requests: provide continuation token from the previous response.

Channels with no community tab return an empty results list (HTTP 200, not an error). Like counts are display strings (e.g. 1.2K) and are null when hidden — never 0.

Freshness: cached for 5 minutes.

Credit cost: 1 credit per page.
