chore(drivers): ratchet down query-options-erasure test-surface baseline

This PR's sweep removed 7 object:-key erasure sites counted by the
query-options-erasure test-surface aggregate, dropping it 249 -> 242.
Per the ratchet's own instruction (scripts/check-query-options-erasure-ratchet.mjs),
a count that falls must be ratcheted down in the same PR — a ceiling left
above reality silently licenses that many new erasures. Ran
`pnpm check:query-options-erasure --update` and verified the diff touches
only testSurface.sites (249 -> 242), nothing else moved.
