Greptile Summary

This PR regenerates internal/api/client.gen.go against the updated staging OpenAPI spec, replacing the verbose RootModelUnionDictStrAnyListDictStrAny union type (a struct with six marshal/unmarshal helpers) with the simpler type alias RootModelAny = interface{}.

• The old union type and all six associated helper methods (As*, From*, Merge*) are removed; the three corresponding methods on StructuredDataBaseModel_Data are updated to use the new alias.
• No callers outside client.gen.go reference the old type, so there is no downstream breakage.

Confidence Score: 5/5

Safe to merge — the change is confined to a single generated file, the removed type had no callers outside the file, and the simplified alias is a faithful representation of the updated OpenAPI schema.

The diff is a mechanical code-generation update. The old union type was only referenced internally within client.gen.go, so nothing downstream breaks. The new interface{} alias correctly matches the Any schema in the updated spec, and the three surviving helper methods on StructuredDataBaseModel_Data behave identically to their predecessors for well-formed JSON.

No files require special attention.

**No tests added in this PR**

This PR does not include any unit or integration tests. Even for a generated client, a small round-trip test covering `AsRootModelAny` / `FromRootModelAny` on `StructuredDataBaseModel_Data` would help catch regressions if the schema changes again — especially since `RootModelAny` is now `interface{}` and `json.Unmarshal` into an untyped value can silently change the concrete Go type (e.g. numbers become `float64`) in ways that callers might not expect.
