chore(spec): regenerate api-surface snapshot for ADR-0096 exports

The `check:api-surface` gate (run in the TypeScript Type Check job) flagged the
13 new `@objectstack/spec` exports added by ADR-0096 as an intentional additive
API change (0 breaking, 13 added): the ConnectorInstance* auth schemas,
ResolvedConnectorAuth, the ConnectorProvider* / ConnectorMaterialization*
contract, and DeclarativeConnectorEntry(Schema). Regenerate the committed
snapshot. spec-changes.json and the upgrade guide are unaffected.
