DuckDB based VectorStore?

[detro]

DuckDB offers an extension called vss (doc). I'm currently working on a personal project, creating a RAG of personal/local notes/documents, and I resolved to use DuckDB as I want the whole thing to be hosted in a single binary running locally using ollama as the sole dependency.

I'm finding myself using langchaingo, and implement the VectorStore interface (and spending a bunch of time looking at the code of other implementations, to do it in the most "consistent" way possible).

Would you be open to a contribution?
