+### Added
+- **GameHacking.org Cheat Proxy** — Cloudflare Workers middleware (`Scripts/cheat-proxy/`) that scrapes GameHacking.org and returns normalised JSON cheat entries with 24h server-side KV caching; reduces scraper fragility and load on the source site.
+- **Cheat proxy settings** — `useCheatProxy` (default `true`) and `cheatProxyURL` settings allow the proxy endpoint to be enabled/disabled and configured without an app update.
+- **Automatic proxy fallback** — When the proxy is unreachable or returns no results, `GameHackingOrgLookup` transparently falls back to the existing direct HTML scraper.
