Update dependencies and add CLI completions support

- Updated several dependencies in `Cargo.lock` and `Cargo.toml`, including `anyhow`, `tempfile`, `clap`, and others to their latest versions for improved functionality and security.
- Introduced a new `CompletionsCommand` in the CLI to support shell completions, enhancing user experience by allowing users to generate command completions for various shells.

These changes aim to keep the project dependencies up-to-date and improve the command-line interface usability.
