Fix CLI dimension field mismatch + add TurboQuant to README (#309)

* fix(cli): correct field name mismatch in create and benchmark commands

The CLI passed `dimension` (singular) but the native NAPI binding
expects `dimensions` (plural). Also fix `db.save()` call which doesn't
exist on VectorDBWrapper — use `storagePath` constructor option instead.

Fixes #307

+## TurboQuant — KV-Cache Compression
+
+Reduce inference memory by 6-8x with <0.5% quality loss:
+
+```typescript
+import { simd } from '@ruvector/ruvllm/simd';
+
+// TurboQuant compresses KV-cache entries at 2-4 bit precision
+// with per-channel asymmetric quantization (scale + zero-point).
+// Eviction policies (H2O, Sliding Window, PyramidKV) keep the
+// most important tokens in cache during long-context generation.
+
+// Supported bit widths: 2-bit (32x), 3-bit (10.7x), 4-bit (8x), 8-bit (4x)
+```
+
+| Bits | Compression | Perplexity Loss | Use Case |
+|------|-------------|-----------------|----------|
+| 2-bit | 32x | ~2% | Maximum compression, edge devices |
+| 3-bit | 10.7x | <1% | Balanced — recommended for most uses |
+| 4-bit | 8x | <0.5% | High quality, long-context inference |
+| 8-bit | 4x | ~0% | Baseline quantization |
