Search Custom Object Records based on the provided filters.

Results are ordered by inserted_at ascending, then id ascending (oldest first).

Supports two pagination methods, supplied in the request body alongside filters:

• Cursor-based (recommended): pass cursor (with limit) to page forward. The response
  includes a metadata object whose next_cursor is null on the last page. Cursor
  pagination is triggered automatically when a cursor value is provided; cursor and
  offset cannot be combined. The cursor encodes only the sort position (inserted_at,
  id) — resend the same filters on every page.
• Offset-based (deprecated): pass offset (with limit).
