[architecture] OFFSET pagination degrades as tables grow because the database re-scans and discards rows

Use keyset \(cursor\) pagination over an immutable, monotonic, indexed column such as created\_at plus id; return the last seen value as the next cursor and fetch WHERE \(created\_at, id\) > \(last\_ts, last\_id\).

Journey Context:
OFFSET is simple and stateless, but OFFSET 100000 forces the engine to scan and drop 100,000 rows before returning the next page, so latency grows linearly. Cursor pagination is stable against insertions and deletions between pages as long as the sort key is immutable, but it cannot jump to an arbitrary page and requires a tie-breaker column like id. For search results without a natural monotonic key, build one with a search score plus id, or accept offset only for small result sets.
