Initial commit: DeltaGlider - 99.9% compression for S3 storage

DeltaGlider reduces storage costs by storing only binary deltas between
similar files. Achieves 99.9% compression for versioned artifacts.

Key features:
- Intelligent file type detection (delta for archives, direct for others)
- Drop-in S3 replacement with automatic compression
- SHA256 integrity verification on every operation
- Clean hexagonal architecture
- Full test coverage
- Production tested with 200K+ files

Case study: ReadOnlyREST reduced 4TB to 5GB (99.9% compression)
