/**
 * `api_logs` repository — structured log of the user-facing memory
 * operations (`memos_search`, `memory_add`). Mirrors the legacy
 * `memos-local-openclaw` plugin's table so the new viewer can render
 * the same rich JSON payloads (candidates, filtered, hub results,
 * ingestion stats, …).
 *
 * Schema: see `core/storage/migrations/007-api-logs.sql`.
 *
 * Write path: invoked synchronously inside the pipeline whenever we
 * complete a `memory.search` retrieval (adapter tool bridge) or an
 * `agent_end`-driven ingest turn.
 *
 * Read path: paginated newest-first by `called_at`. The viewer tails
 * the table via `GET /api/v1/api-logs`.
