This commit introduces a TDD testing framework for the `collect` commands and resolves a build failure.
- A `TDD/` directory has been added to house tests for the `collect` commands.
- An environment variable `BORG_PLEXSUS=0` has been implemented to enable a mock mode, which prevents external network calls during testing.
- The `collect` commands have been updated to use the command's output streams, allowing for output capturing in tests.
- A `pkg/mocks` package has been added to provide mock implementations for testing.
- The `.gitignore` file has been updated to exclude generated `.datanode` files.
- The "flag redefined" build error has been fixed by refactoring the root command initialization in `cmd/root.go` to prevent duplicate flag definitions.
This commit introduces a new `collect github` command with two subcommands:
- `repo`: Clones a GitHub repository. This functionality was previously under the `collect git` command.
- `release`: Downloads assets from the latest GitHub release of a repository.
The `release` subcommand supports the following features:
- Version checking against a provided version string using the `--version` flag.
- Downloading a specific file from the release using the `--file` flag.
- Downloading all assets from the release and packing them into a DataNode using the `--pack` flag.
- Specifying an output directory for the downloaded files using the `--output` flag.
This commit also resolves a merge conflict by restructuring the `collect` command and its subcommands. The `collect git` and `collect github-release` commands have been consolidated under the new `collect github` command to provide a more organized and user-friendly command structure.
