Get Schema Records
Returns a sample of records from a schema on a connection.
The sample is intended for previewing the shape and values of data before
committing to a sync configuration, not for full data export.
> 🚧 The sample is not guaranteed to be representative of the full dataset.
> Row selection is implementation-defined and may differ across connection
> types.
> 📘 If the schema's field definitions are stale, refresh them first with
> [`POST /api/connections/{id}/schemas/refresh`](../../../../../../api-reference/schemas/refresh) to ensure
> the sample aligns with the current schema structure.
