Cloudflare: type can now return "d1"

Cloudflare's AI Search API can now return "d1" as a value for result.type on POST /accounts/{account_id}/ai-search/instances, adding to the existing "r2", "web-crawler" and null values. The change, described as additive by producer-side tools, also applies to the GET, PUT and DELETE instance endpoints and to the namespaced instance endpoints, and breaks exhaustive switches, strict parsers and generated client enums that lack a "d1" branch.
