⚡ Bolt: [performance improvement] VectorStore O(N^2) insertion bottleneck fix

* Replaced `np.vstack` on every array insertion with a lazy memory buffer (`self._unmerged_vectors`)
* Vectors are now batched into a single `np.vstack` block append before critical operations (`search`, `save`, `compact`, `_build_annoy_index`)
* Massively reduces CPU overhead and avoids O(N^2) repeated array copying
* Benchmark dropped from ~26 seconds to ~9.4 seconds for 10,000 array appends.
* Fixed syntax error caused by Safety missing the database locally.
