feat: Add TDD framework and fix build error

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.
