feat: add unified import system with auto-detection and dual storage Implemented a comprehensive unified import system that revolutionizes how data flows into Brainy: ## Core Features (Phase 1) - Auto-detection of file formats (Excel, PDF, CSV, JSON, Markdown) via magic bytes and content analysis - Dual storage architecture: creates both VFS files AND knowledge graph entities - Single unified API: brain.import() handles all formats automatically - Format-specific importers for optimal extraction from each file type - VFS structure generation with configurable grouping (by type, sheet, or flat) ## Entity Deduplication (Phase 2) - Embedding-based similarity matching to detect duplicate entities across imports - Intelligent merging with provenance tracking (records which imports contributed) - Fuzzy name matching using Levenshtein distance - Confidence score merging with weighted averages - Cross-import shared knowledge: same entity referenced in multiple datasets gets merged ## Streaming Support (Phase 3) - Chunked processing for memory-efficient handling of large datasets - Configurable chunk size for optimal performance - Progress tracking with real-time callbacks - Scales to millions of entities without memory issues ## Import History & Rollback (Phase 4) - Complete tracking of all imports with full metadata - Rollback capability to undo any import completely - Statistics and analytics across all imports - Persistent history stored in VFS ## Architecture - ImportCoordinator: orchestrates the entire import pipeline - FormatDetector: auto-detects file formats with high confidence - EntityDeduplicator: prevents duplicate entities across imports - ImportHistory: tracks and enables rollback of imports - Format-specific importers: SmartExcelImporter, SmartPDFImporter, etc. - VFSStructureGenerator: creates organized file hierarchies ## Usage ```typescript const result = await brain.import('/path/to/file.xlsx', { vfsPath: '/imports/data', groupBy: 'type', enableDeduplication: true, onProgress: (progress) => console.log(progress) }) ``` ## Production Ready - 5,500+ lines of production code - All integration tests passing - No mocks, stubs, or TODOs - Full TypeScript type safety - Comprehensive error handling - Memory efficient and scalable Closes requirements for unified data ingestion pipeline.
