}List messages in a conversation
List a conversation’s messages, cursor-paginated. When the conversation is backed by a DM channel this returns the LIVE two-way thread (both parties’ messages, source: 'live'); conversations without a connected chat — or a failed upstream read — fall back to the stored mirror (source: 'stored', outbound + system messages only). A conversation the tenant does not belong to is reported as 404.
