feat: Universal Import with intelligent type matching (v2.1.0)
✨ ONE universal import method for everything - Auto-detects files, URLs, and raw data - Intelligent noun/verb type matching using embeddings - Support for JSON, CSV, YAML, and text formats - Zero configuration required 🧠 Intelligent Type Matching - Uses semantic embeddings to match 31 noun types - Automatically detects 40 verb relationship types - Confidence scores for type predictions - Caching for improved performance 📦 Import Manager - Centralized import logic with lazy loading - Integrates NeuralImportAugmentation for AI processing - Proper CSV parsing with quote handling - Basic YAML support 🎯 Simplified API - brain.import() - ONE method that handles everything - Auto-detection of URLs and file paths - Backwards compatible with existing code - Clean, modern, delightful developer experience 📚 Documentation - Comprehensive import guide in docs/guides/import-anything.md - Examples for every format and use case - Philosophy of simplicity and zero config ✅ Tests - Full unit test coverage for import functionality - Type matching tests for all 31 nouns and 40 verbs - Tests for CSV, YAML, JSON, and text formats BREAKING CHANGES: None - fully backward compatible
