fix: preflight complete archives before mutation

Plan and validate every internal ZIP, Zip4j, and SevenZipJBinding entry and final conflict target before any archive output mutates the filesystem. Preserve raw RAR list entry whitespace for strict validation and keep any non-matching package owner marker immutable while direct scoped outputs continue without marker reissuance.
