Typing Stubs for zstd

The `types-zstd` library provides static type annotations for the `python-zstandard` compression library, enabling type checkers like MyPy to validate the correct usage of `zstd` in Python projects. It is part of the `typeshed` project, which regularly updates stubs to reflect changes in popular Python libraries and new Python versions. The current version is 1.5.7.3.20260408.
