This commit introduces a TDD testing framework for the `collect` commands.
- A `TDD/` directory has been added to house the tests.
- 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.
This commit introduces a new `collect github repos` command to the CLI. This command allows users to fetch all public repositories for a given user or organization.
Key changes:
- Added a new command file `cmd/collect_github_repos.go`.
- Updated the documentation in `docs/index.md` to include the new command and the `collect github release` command.
