Design for a super-user SQL notebook qbit: read-only by default with a
gated, audited write mode over any QQQ RDBMS backend; notebooks with
versions, parameters and snapshots; REST API under
/qqq/v1/sql-workbench; Next UI SQL_WORKBENCH widget. Adds license,
notice, policy files and CODEOWNERS like the sibling qbits.
