This commit introduces several maintenance improvements to the repository.
- A `go.work` file has been added to define the workspace and make the project easier to work with.
- The module path in `go.mod` has been updated to use a GitHub URL, and all import paths have been updated accordingly.
- `examples` and `docs` directories have been created.
- The `examples` directory contains scripts that demonstrate the tool's functionality.
- The `docs` directory contains documentation for the project.
- Tests have been added to the `pkg/github` package following the `_Good`, `_Bad`, `_Ugly` convention.
- The missing `pkg/borg` package has been added to resolve a build error.
This commit introduces a new `collect website` command that recursively downloads a website to a specified depth.
- A new `pkg/website` package contains the logic for the recursive download.
- A new `pkg/ui` package provides a progress bar for long-running operations, which is used by the website downloader.
- The `collect pwa` subcommand has been restored to be PWA-specific.
