Mem0 - Several things break in the Node.js OSS version of mem0 at once.

## The fix

All three were fixed and the issue closed as resolved, per maintainer kartik-mem0. (1) Supabase PGRST205: the memory_migrations table lookup is now handled with a graceful fallback, but you still have to run the SQL migration from the Supabase provider docs against your project yourself; the docs steps alone did not create that table. (2) Redis toString crash: fixed in an earlier PR by setting embedding dims properly in the constructor, so upgrade the mem0 package and pass your embedding dims explicitly in the Redis vector-store config. (3) pgvector: it was genuinely missing from the factory and was added in PR #3997 (merged), so upgrade to a release that includes it before trying to configure pgvector as your store.
