CLI: uc2 -w [-L level] archive.uc2 files... Creates UC2 archives with long filename tags and the built-in 49KB SuperMaster dictionary for improved compression via LZ77 prefix matching. Library: uc2_compress_ex() accepts master data to pre-fill the sliding window and hash chains. uc2_get_supermaster() decompresses the embedded super.bin. uc2_compress() unchanged (backward compatible, NoMaster). Tests: 5 SuperMaster roundtrip tests, CLI create/extract CTest script.
