chore: recovery checkpoint - v3.0 API successfully recovered

CRITICAL CHECKPOINT - DO NOT PUSH TO GITHUB

Recovery Status:
- Successfully recovered brainy.ts from compiled JavaScript
- All core v3.0 API methods functional (add, get, update, delete, relate, find, etc.)
- Neural subsystem intact (562KB embedded patterns, NLP working)
- Augmentation pipeline operational (20+ augmentations)
- HNSW clustering system complete
- Triple Intelligence compiled (needs constructor fix)
- Test suite validates functionality

Changes preserved:
- 898 files with changes from last 3 days
- 144,475 insertions
- All augmentation improvements
- All test coverage enhancements
- Complete v3.0 feature set

This is a LOCAL checkpoint only - contains recovered work after corruption incident.

+/**
+ * 🧠 Pre-compute Pattern Embeddings Script
+ *
+ * This script pre-computes embeddings for all patterns and saves them to disk.
+ * Run this once after adding new patterns to avoid runtime embedding costs.
+ *
+ * How it works:
+ * 1. Load all patterns from library.json
+ * 2. Use Brainy's embedding model to encode each pattern's examples
+ * 3. Average the example embeddings to get a robust pattern representation
+ * 4. Save embeddings to patterns/embeddings.bin for instant loading
+ *
+ * Benefits:
+ * - Pattern matching becomes pure math (cosine similarity)
+ * - No embedding model calls during query processing
+ * - Patterns load instantly with pre-computed vectors
