Completes Phase 3 (Modernized Master-Block Deduplication). SimHash (uc2_simhash.h): 64-bit locality-sensitive fingerprint using 4-byte shingles. Similar files produce fingerprints with small Hamming distance. Detects patched executables (16 bytes changed in 8KB: dist<=8), slightly edited documents, and minor file revisions. 6 unit tests. Delta compression (uc2_delta.h): binary diff with COPY (from source) and INSERT (new data) instructions. Hash-based source matching for fast encoding. 16KB file with 96 patched bytes: >50% delta size savings. Full round-trip verified for identical, different, patched, appended, and empty inputs. 6 unit tests. All Phase 3 items now complete: - [x] Content-fingerprint grouping (FNV-1a) - [x] Custom master-block generation - [x] MASMETA cdir records - [x] SuperMaster-compressed masters - [x] CDC with Gear rolling hash - [x] Merkle DAG content addressing - [x] Cross-archive block store - [x] Near-duplicate detection (SimHash) - [x] Delta compression
