fix: resolve Zod v4 record schema compatibility issues

- Update z.record() calls to use proper key-value type parameters
- Fix TypeScript compilation errors in Smithery-compatible index.ts
- Ensure compatibility with Zod v4.0.10 API requirements

This resolves build failures and ensures the Smithery deployment
configuration compiles successfully.
