feat: add ImageHandler with EXIF extraction and comprehensive MIME detection (v5.2.0)
Implements Phase 1.5 (Comprehensive MIME Type Detection) and adds built-in image processing support to IntelligentImportAugmentation. **New Features:** - ImageHandler: Extracts image metadata (dimensions, format, color space) using sharp - EXIF extraction: Camera data, GPS, timestamps using exifr library - Support for JPEG, PNG, WebP, GIF, TIFF, BMP, SVG, HEIC, AVIF formats - MimeTypeDetector: Unified MIME type detection with magic byte support - FormatDetector: Enhanced with image format detection via MIME + magic bytes **Architecture Fixes:** - Fixed brain.import() augmentation pipeline integration (src/brainy.ts:3140-3154) - Added parameter spreading for ImportSource objects to enable augmentation access - Fixed metadata propagation through ImportCoordinator to final results - Added augmentation data check in ImportCoordinator.extract() **Integration:** - ImageHandler registered as built-in handler alongside CSV, Excel, PDF - Images import as 'media' entities with 'image' subtype - Full metadata preserved in knowledge graph entities - Configuration options: enableImage, extractEXIF, imageDefaults **Test Coverage:** - 15 integration tests (image-import.test.ts) - 100% passing - 27 unit tests (image-handler.test.ts) - 100% passing - Format detection tests for all supported image types - Error handling and resilience tests **Breaking Changes:** None - backward compatible Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
