Return type for Connector.onCreateLink. Identical to
NewLinkWithNotes except channelId may be omitted: the platform
already knows which channel the user composed into (from the create
draft) and auto-fills channelId from it when omitted. Connectors
building links directly for integrations.saveLink()/saveLinks() (sync,
backfill, webhook ingestion) must use NewLinkWithNotes instead,
where channelId is required — that path has no equivalent auto-fill.
