- removed usage of the `helm` CLI within the `kubenix` CLI
This simplifies design by removing overlapping responsibilities but means extra functionality provided by the `helm` CLI is no longer available; specifically:
- hooks are no longer ordered (but can still be excluded with `noHooks`)
-`helm` subcommands (e.g., `list` or `rollback`) will not be able to operate on resources
### Added
- the CLI now prunes resources and performs an interactive diff by default
