## Description
- Also started storing the embedding size and version in the table. This
will come handy while comparing overall size when different compression
and serialization formats are used..
- Also, it can be used to smartly auto-download the embeddings or inform
the user about approximate size when they decide to enable indexing or
search on a particular client.
## Tests
✅ Verified that embedding fetch and store is working fine.
✅ Verified that embeddings/diff API is working fine.
