This commit represents a significant architectural overhaul of vaultik: Database Schema Changes: - Switch files table to use UUID primary keys instead of path-based keys - Add UUID primary keys to blobs table for immediate chunk association - Update all foreign key relationships to use UUIDs - Add comprehensive schema documentation in DATAMODEL.md - Add SQLite busy timeout handling for concurrent operations Streaming and Performance Improvements: - Implement true streaming blob packing without intermediate storage - Add streaming chunk processing to reduce memory usage - Improve progress reporting with real-time metrics - Add upload metrics tracking in new uploads table CLI Refactoring: - Restructure CLI to use subcommands: snapshot create/list/purge/verify - Add store info command for S3 configuration display - Add custom duration parser supporting days/weeks/months/years - Remove old backup.go in favor of enhanced snapshot.go - Add --cron flag for silent operation Configuration Changes: - Remove unused index_prefix configuration option - Add support for snapshot pruning retention policies - Improve configuration validation and error messages Testing Improvements: - Add comprehensive repository tests with edge cases - Add cascade delete debugging tests - Fix concurrent operation tests to use SQLite busy timeout - Remove tolerance for SQLITE_BUSY errors in tests Documentation: - Add MIT LICENSE file - Update README with new command structure - Add comprehensive DATAMODEL.md explaining database schema - Update DESIGN.md with UUID-based architecture Other Changes: - Add test-config.yml for testing - Update Makefile with better test output formatting - Fix various race conditions in concurrent operations - Improve error handling throughout
