Notes

• If no emails match the filters within the poll window, the node returns null and the workflow does not trigger.
• readStatus, label, sender, subjectContains, and hasAttachment combine into a single Gmail search query; matches are further checked against the precise poll window since Gmail's date filter is day-granular.
• Emits one item containing emails (array) and a summary (count, subjects, senders, pollInterval, polledAt).
• If markAsRead is set, matched emails have their UNREAD label removed (best-effort); if includeAttachments is set, attachments are downloaded into the item's binary data.
