About nano-string-utils

I'm adding nano-string-utils to the String section. This is an ultra-lightweight string utilities library with the following key features:

• Zero dependencies - No supply chain vulnerabilities or bloat
• Tree-shakeable - Each function is independently importable with minimal overhead (< 1KB per function)
• Fully typed - Complete TypeScript support with template literal types and branded types
• 48 utility functions - Comprehensive string manipulation, validation, and transformation functions
• Production ready - 100% test coverage, actively maintained with CI/CD
• Modern - Built for ES2022+ with ESM and CJS support
• Fast - Competitive performance with popular alternatives like lodash and es-toolkit

The library has been actively maintained since its release and provides a modern, dependency-free alternative to libraries like lodash/underscore.string with excellent bundle size characteristics.
