Add CLIENT SETNAME to Valkey client for connection identification

Summary

The llmware Valkey embeddings integration creates a GlideClient without setting a client_name. This means connections appear anonymous in monitoring tools like CLIENT LIST and Valkey Admin.

Suggested Fix

In tests/embeddings/test_valkey_embeddings.py (line ~37), add client_name to the GlideClientConfiguration:

cfg = GlideClientConfiguration(
    [NodeAddress(host, port)],
    client_name="llmware_embedding_client",
)

Why This Matters

When monitoring a Valkey server with multiple connected applications, CLIENT LIST shows each connection's name. Without a client name, operators cannot distinguish llmware connections from other anonymous clients. This is especially important in production environments with ElastiCache where multiple services share the same Valkey cluster.

Setting client_name sends a CLIENT SETNAME command on connection, making the connection identifiable in:

• CLIENT LIST output
• Monitoring dashboards (e.g., Valkey Admin)
• CloudWatch metrics (ElastiCache)

Naming Convention

Suggested client name: llmware_embedding_client

Pattern: {project}_{purpose}_client

• llmware = project name
• embedding = purpose (embedding storage and retrieval)
• _client = convention (matches Valkey Admin naming pattern)
