/**
* Checks if a value can be deeply merged into, i.e. it is a plain object or an array.
*
* This function is used in `merge`, `mergeWith`, and `toMerged` to decide whether
* the source value should be merged into the existing target value recursively,
* preserving the target's structure, instead of replacing it.
*
* @param value - The value to check.
* @returns `true` if the value is a plain object or an array, otherwise `false`.
