Added large data sync support to the New and Updated Records trigger:

• Added opt-in batching to the New and Updated Records trigger, dispatching each changed record individually or in configured batches; enabling it changes the shape a downstream step receives
• Added an optional Look-back Date input for performing an initial sync of records. The initial sync begins on the first recurrence and backfills every record modified on or after the specified date, seeding each once; later recurrences are unaffected. Leave it empty to start from the first recurrence with no backfill
