- Remove unused imports and variables across multiple files
- Fix React set-state-in-effect by suppressing with eslint-disable
- Wrap handleFile in useCallback to stabilize hook dependencies
- Remove dead MetaItem component from game-page-client
- Add public/sw.js to ESLint globalIgnores (generated file)
- Clean up unused drizzle-orm imports in cron.ts, dashboard-public.ts
- Remove unused _configured flag from r2-client.ts
