Make Reference Queries Inspectable

swap-sqlite-driver bundled two different goals: replacing the crash-prone SQLite driver and extracting SQL into inspectable artifacts. The driver swap has landed; query extraction remains valuable, but it should now be evaluated on inspectability and maintainability rather than native-driver stability.

Make the reference implementation's durable SQLite query surface reviewable without forcing readers to infer it from string templates embedded across large JS/TS modules.

The reference implementation SHALL keep static SQLite statements that define durable reference behavior in named query artifacts or an equivalent named registry. Query identifiers SHALL be stable enough for reviewers, tests, and future operator tooling to refer to them directly.
