Mixme Object Merger

Mixme is a JavaScript/TypeScript library (currently at v2.0.2) designed for recursively merging and manipulating JavaScript objects. It provides immutable merging via `merge` and mutable in-place modification via `mutate`. Key differentiators include its zero-dependency footprint, minimal size, and pure function approach for `merge`. It offers comprehensive TypeScript type definitions and supports both ES Modules (ESM) and CommonJS environments. While a specific release cadence isn't explicitly published, the project appears actively maintained with a streamlined release process via GitHub Actions. A notable behavior is that arrays are always overwritten during merges, not recursively combined, which is a common point of confusion for users expecting deep array merging.
