Typing stubs for psutil

The `types-psutil` package provides PEP 561-compliant typing stubs for the `psutil` library, enabling static type checkers like MyPy and Pyright to analyze code that uses `psutil` for system and process utilities. As part of the typeshed project, its release cadence is tied to typeshed's updates and the `psutil` library's own releases, ensuring up-to-date type coverage. The current version is 7.2.2.20260408.
