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 refactors the repository collection functionality to use the new `DataNode` package instead of the old `trix` package.
The `collect` and `all` commands have been updated to use the new `vcs` package, which clones Git repositories and packages them into a `DataNode`. The `trix` package and its related commands (`cat`, `ingest`) have been removed.
