The module docstring includes a "MEMORY:" line that looks like an internal note rather than user-facing documentation. Please remove it or replace it with a normal summary sentence so the docstring is consistent and not confusing to readers.

Suggested change

	MEMORY: This file contains a simple merge sort implementation in Python.
	This module contains a simple merge sort implementation in Python.

The docstring says this returns "a new sorted array", but for inputs of length 0/1 the function returns the original list object (return arr). Either update the docstring to not promise a new list, or ensure the base case also returns a new list (e.g., a shallow copy) so the return semantics are consistent.

The PR title/description don’t mention adding a new root-level merge_sort.py module (and README content updates). Please update the PR description to reflect the intent/scope of these changes so reviewers and release notes are accurate.
