Meilisearch March updates

What this post added

This post announces the release of replicated sharding directly in the Meilisearch engine (v1.37), a major advancement for distributed and resilient search. It highlights this as a stepping stone to one-click replication in the Cloud UI and notes its availability under the Enterprise edition. The post also mentions that the HNSW-backed vector store (Hannoy) is now stabilized and the legacy `vectorStoreSetting` has been removed, with automatic migration during dumpless upgrades. v1.38 further improves embedding indexing performance by eliminating unnecessary full database scans for updates, fixing intermittent connection errors with remote embedders, and resolving an edge case with task and batch deletion.
