Inline Source CLI: HTML Resource Inliner

The `inline-source-cli` package offers a dedicated command-line interface (CLI) for the `inline-source` library, a utility designed to embed external resources such as CSS stylesheets, JavaScript code, and image data directly into an HTML file. This functionality is crucial for scenarios requiring self-contained HTML documents, such as preparing email templates, optimizing static site assets for single-file deployment, or creating portable web components. The package is currently at stable version 2.0.0, with a release cadence that appears driven by dependency updates or minor feature enhancements like the addition of stdin support. Its primary advantage lies in providing a straightforward, opinionated command-line tool that abstracts away the programmatic complexity of resource inlining, making it easy to integrate into existing build scripts and CI/CD pipelines without writing custom JavaScript code. Developers can quickly achieve asset optimization and delivery benefits without deep diving into the underlying library's API, using standard shell commands.
