fix(logging): address review feedback and rebase against origin/main

- Revert ProcessDependencies, ValidateAgainstSchema, ValidateAgainstSingleSchema
  to original 2-arg public signatures; use slog.Default() internally
- Use slog.Warn in cmd/helm/helm.go instead of fmt.Fprintf(os.Stderr)
- Call slog.SetDefault(logger) in newRootCmdWithConfig so global slog
  functions (e.g. LogIgnorePluginLoadErrorFilterFunc) use the configured handler
- Fix callers that still passed nil logger after public API revert
- Resolve rebase conflicts with origin/main (map[string]any, slices.Backward,
  plugin.LoadAllDir improvements)
