Summary

• Adds a searchResponsePartial schema as a third oneOf variant in searchResult
• Fixes deserialization failures when responseFields strips required fields like hits

Context

#6199 auto-infers discriminator fields from unique required properties. For searchResult, this gives searchResponse a hits discriminator and searchForFacetValuesResponse keeps its explicit facetHits discriminator.

When a user sets responseFields to a subset excluding hits (e.g. ["nbHits"]), the API returns a valid search response without hits. Both discriminator checks fail → deserialization throws InvalidDataException. Affects all languages with discriminator-guarded oneOf deserialization.

Fix

searchResponsePartial has the same properties as searchResponse (baseSearchResponse + SearchPagination + hits/query/params/extensions) but no required fields. Since inferDiscriminatorFields can't compute unique required fields for it, no discriminator is inferred. sortOneOfs places it last (variants with discriminators sort first).

Deserialization order becomes:

1. searchForFacetValuesResponse — discriminator facetHits → tried first
2. searchResponse — discriminator hits → tried second
3. searchResponsePartial — no discriminator → unconditional catch-all

No generator changes needed.
