fix: Resolve TypeScript build errors for production deployment

- Add type assertion for SurrealDB query results in debug/nodes route
- Install @types/three for Three.js type definitions
- Exclude tests directory from TypeScript compilation
- Wrap useSearchParams in Suspense boundary on login page (Next.js 16 requirement)

All routes now build successfully for production deployment.
