Add build testing and pre-commit hooks

- Add test-build.js script to verify standalone build locally
- Add pre-commit hook with security, build, and test checks
- Copy required-server-files.json to root of standalone for Amplify
- Add husky for automatic pre-commit validation

This ensures we test builds locally before pushing
