• Changed 1G1R default dryRun value to true to avoid modifying user files by default.
• Updated extractCleanTitle in one_g_one_r.dart to preserve multi-disc tags (Disc 1, Disc A, CD 1, etc.).
• Filtered companion and sidecar files (.cue, .m3u, .sav, save states, track .bin files) from being grouped into duplicate candidates.
• Added pre-release penalty score so commercial releases take priority over Beta/Proto/Demo/Sample builds.
• Refactored zip extraction in compressor.dart to use InputFileStream and OutputFileStream for streamed/chunked reading and writing to prevent OOM errors on large archives.
• Explicitly throw UnsupportedError when 7Z format is requested.
• Updated README.md and core/bin/openrom.dart help documentation to specify supported archive formats and clarify generic patching vs DCP patching options.
• Added unit tests in core/test/ for 1G1R improvements and compressor behavior.
