fix: Use HTTP API for vision tests instead of non-existent CLI

The `shimmy vision` CLI subcommand doesn't exist - vision is only
accessible via HTTP API at POST /api/vision. Updated tests to:

- Start shimmy server in background
- Wait for server health check
- POST to /api/vision endpoint with base64 image
- Check for valid response

Also updated summary table to reflect new test structure.
