## Summary - Deletes `use-throttler.ts` — an envelop plugin that was never registered in the GraphQL config plugin chain (dead code since introduction) - Removes the `graphql-rate-limit` dependency from `package.json` (only consumer was the deleted file) API rate limiting continues to work via `ThrottlerService` in the query runner layer (for API key auth). Global coverage should be handled at the infrastructure level (Cloudflare). ## Test plan - [x] Confirmed no imports of `useThrottler`, `ThrottlerPluginOptions`, or `UnauthenticatedError` from this file exist anywhere in the codebase - [x] `graphql-rate-limit` has no other consumers Made with [Cursor](https://cursor.com) Co-authored-by: Cursor <cursoragent@cursor.com>
