Vulnerabilidades de @theecryptochad/merge-guard

@theecryptochad/merge-guard has Prototype Pollution in its deepMerge() function

## Summary `@theecryptochad/merge-guard` versions prior to 1.0.1 are vulnerable to Prototype Pollution via the `deepMerge()` function. An attacker who controls the source object can inject `__proto__` keys that mutate `Object.prototype`, affecting all objects in the Node.js runtime. ## Details The `deepMerge()` function recursively merges two objects without sanitizing reserved property keys (`__proto__`, `constructor`, `prototype`). When a source object contains a `__proto__` key, its value is assigned to `target.__proto__`, which JavaScript engines interpret as a write to `Object.prototype`. ## Proof of Concept ```js const { deepMerge
