Adds TypeScript type definitions for the new `web_search` binding kind:
- WebSearch (abstract class with single `search()` method)
- WebSearchSearchOptions (query + optional limit)
- WebSearchResult (url, title, description?, lastModifiedDate?,
imageUrl?, faviconUrl?)
- WebSearchResponseMetadata (query, requestId, latencyMs)
- WebSearchSearchResponse ({ items, metadata })
The container types are named `WebSearchSearchOptions` /
`WebSearchSearchResponse` to avoid a name collision with the
pre-existing `WebSearchOptions` type in ai.d.ts (used by the
OpenAI-compatible `web_search_options` field on Workers AI chat
completions).
Discovery-only by design: no `snippets`, `content`, or
`scoringDetails` fields. Pay-per-Crawl alignment -- callers fetch
URLs themselves via the global `fetch()` API if they need bodies.
`lastModifiedDate` is exposed as a naive ISO-8601 datetime string
(e.g. `"2025-11-30T04:39:48"`) when the upstream catalog knows it.
Snapshots are the upstream baseline with only the appended
`defines/web-search.d.ts` block; they were not full-regenerated to
avoid sweeping in unrelated drift.

types look fine - should unblock miniflare stuff?

this will be a remote only binding, so this pr can wait for the repo to be unlocked. meanwhile on workers sdk repo we can continue without typegen |
