Add flux-plunger controller to automatically fix HelmRelease resources
with "has no deployed releases" error.
The controller watches HelmRelease resources and performs the following:
- Detects HelmRelease with "has no deployed releases" error
- Suspends the HelmRelease with flux-client-side-apply field manager
- Deletes the latest Helm release secret
- Updates annotation with processed version to prevent recursive deletion
- Unsuspends the HelmRelease to allow Flux to retry
Special handling for suspended HelmRelease:
- If suspend=true and latest+1==processed: removes suspend
- Otherwise: skips processing as suspended by external process
