Function SetEnvVars

pkg/utils/extensions/extensions.go:176–204

SetEnvVars applies custom Env entries from the given extensions (mounted under baseDir) into envMap, expanding placeholders like ${image_root} against baseDir. Names reserved for operator use or covered by dedicated fields are skipped; overrides are logged as warnings.
