Introducing es-toolkit/compat

We're introducing es-toolkit/compat, a new module designed as a drop-in replacement for lodash. It replicates lodash's API, making it easier to switch between the two libraries.

es-toolkit/compat is undergoing rigorous testing using real lodash test cases. Initial benchmarks suggest it's typically 5% slower and increases bundle size by 10% compared to the original es-toolkit.

This module is intended to facilitate a smooth transition and should be replaced with the original es-toolkit for optimal performance once migration is complete.

For more information, see our compatibility documentation.
