RETRIEVAL_MODE not respected

[rfmsanz-ethan]

When trying to use an .env file for arguments, the retrieval mode isn't respected.

I haven't looked at the source code thoroughly, but it seems that config.py has MemoryEngineConfig which reads MEMORY_RETRIEVAL_MODE from the env file, but main.py uses args.retrieval_mode from argparse instead.

I can manually change the hard-coded argument in main.py, but that kind of defeats the point of an argument:

    parser.add_argument(
        "--retrieval-mode",
        default="smart_vector",
        choices=["claude", "smart_vector", "hybrid"],
        help="Memory retrieval strategy (default: smart_vector)\n"
             "- claude: Use Claude for every retrieval (high quality, high cost)\n"
             "- smart_vector: Intelligent vector search with metadata (fast, smart)\n"
             "- hybrid: Start with vector, escalate to Claude for complex queries"
    )

Also, start_server.py doesn't forward arguments, so to use CLI arguments, one would have to invoke main.py directly.

Unless I'm just missing something?

No my friend, you are not missing anything, in fact, I implemented the other retrieval methods but never tested. I ended up working on the smart vector retrieval mode and forgot to properly make the retrieval methods configuration work properly.

If you can see clearly any solution for this I would love to hear about, otherwise I'll dive into this and get back to you as soon as I can.
