Function extractRuntimeImportPaths

pkg/workflow/runtime_import_validation.go:40–86

extractRuntimeImportPaths extracts all runtime-import file paths from markdown content. Returns a list of file paths (not URLs) referenced in {{#runtime-import}} macros. URLs (http:// or https://) are excluded since they are validated separately.
