sqlite-utils 4.2.1

This article announces the release of sqlite-utils 4.2.1, a Python CLI utility and library for manipulating SQLite databases. The release fixes a crashing bug introduced in version 4.2, which occurred because the code used 'from typing_extensions import Self' but the typing-extensions package was not listed as a dependency. It was only installed via dev dependencies, so when using 'uvx sqlite-utils' directly, the package was missing. The fix also includes a smoke test to ensure the CLI works without dev dependencies, using 'uv run --isolated --no-default-groups sqlite-utils --help'. This is a technical update for developers using sqlite-utils.
