Fixes#2355
In Helm 4, the --validate and --dry-run flags are mutually exclusive.
When using kustomize/chartify charts with helmfile diff --validate,
the code was adding both --validate AND --dry-run=server to the
helm template command, causing the error:
Error: if any flags in the group [validate dry-run] are set none
of the others can be; [dry-run validate] were all set
The fix checks if --validate is already set before adding --dry-run=server.
Since --validate already provides server-side validation (it was deprecated
in favor of --dry-run=server in Helm 4), adding --dry-run=server is
redundant when --validate is present.
Changes:
- Add !opts.Validate condition to processChartification() in state.go
- Add comprehensive unit tests for validate/dry-run mutual exclusion
- Add integration test with kustomize chart to prevent regression
