tooling(gates): pin the new reproduction file's engine double in the double-contract ledger

`check:engine-double-contract` RETAINED both verbs of the new
`stranded-run-repairability.test.ts` double: it already routes `update` and
`delete` through ObjectQL's own dispatch predicates, so the ledger just had to
learn about the file. Regenerated with `--write`; 2 rows added, 0 lost.

Part of #15358
