Mem0 Python SDK (v2.0.14)

New Features:

• Vector Stores: Add an Oracle AI Vector Search provider (oracledb) with connection pooling, HNSW/IVF indexes, JSON metadata filtering, and six selectable distance metrics (#5358)

Bug Fixes:

• Vector Stores: Translate a "*" filter value in OpenSearch into an exists query for every key, not just identity keys. It was previously ignored or matched literally against the string "*", so a wildcard filter returned nothing (#6522)
• Vector Stores: Re-raise errors from OpenSearch search() instead of returning [], so a transport, auth, or index misconfiguration surfaces instead of looking like zero matches. keyword_search() still degrades on failure, since it is a best-effort BM25 signal (#6519)
• Vector Stores: Guard the text field in Milvus update() behind the _has_bm25_schema check, matching insert(), so updating a memory in a collection without the BM25 text/sparse schema no longer fails (#5705)
