place.stream.playback.getLivePlaylist

Get an HLS CMAF playlist for a live stream. Returns a master playlist when `track` is omitted, or a single-track media playlist when `track` is supplied. The playlist references each segment + per-track init segment via getLiveSegment. Segments come from an in-memory sliding window fed as the stream is ingested (or replicated to this node), so a playlist is only available while the stream is live here.
