### Minor Changes

**Performance Optimizations:**
- Global singleton cache and wallet integration optimization
- Add LRU cache to NodeHnswService (capacity: 1000 entries)
- Add LRU cache to HnswWasmService for memory management
- Add singleton pattern for EmbeddingService
- Reduce default embedding dimension from 3072 to 768
- Memory cache eviction to prevent memory leaks

**New Features:**
- findMemoryInQuilt() method for improved quilt file matching
- Enhanced Quilt memory indexing with batch upload support
- MemoryIndex on-chain management utilities
- HNSW index Walrus sync for cross-device restoration
- Incremental index sync by blobId

**Bug Fixes:**
- Fix Quilt batch sync by extracting base quiltId correctly
- Fix batch memory content storage and transaction status detection
- Fix Quilt blobId and use getBlob().files() for correct retrieval

**Architecture Improvements:**
- Memory management with LRU eviction policies
- Optimized cache strategies for embedding and HNSW services
- Improved Quilt file handling and retrieval patterns
