[Bug]: AttributeError in AutoAPI v3 Diagnostics

[MichaelDecent]

Describe the Bug

The AutoAPI v3 diagnostics endpoint (/system/methodz) is throwing an AttributeError because it's trying to access a returns attribute on OpSpec objects that doesn't exist in the v3 implementation.

Steps to Reproduce

Step 1: Start the AutoAPI v3 Application

cd /Users/michaeldecent/Swarmauri/swarmauri-sdk
uv run --directory pkgs/standards/auto_kms auto-kms

Step 2: Wait for Server to Start

You should see output like:

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Application startup complete.

Step 3: Access the Diagnostics Endpoint

Open your browser or use curl to access:

curl http://127.0.0.1:8000/system/methodz

OR visit in browser:

http://127.0.0.1:8000/system/methodz

Expected Result: Error

You'll get a 500 Internal Server Error with this stack trace:

AttributeError: 'OpSpec' object has no attribute 'returns'
  File "autoapi/v3/system/diagnostics.py", line 151, in _methodz
    "returns": sp.returns,
