Feature: OpenAI Vision Integration (PyObjC)

Description

Implement the logic to capture a frame from the AppKit interface and send it to OpenAI's API.

Requirements

1. Image Handling:

   • On "Capture" click:
     • Stop/Pause the live feed update.
     • Store the current frame (in memory).
     • Show "Processing..." (maybe change button text or add a label).

2. OpenAI API Call:

   • Async handling is important to not block the UI thread (spinning beachball).
   • Run the API request in a background thread (threading).
   • Model: gpt-5-mini (fallback gpt-4o-mini).
   • Prompt: "What is this item? Please provide a brief description."

3. Response Handling:

   • When response returns, schedule a UI update on the main thread (performSelectorOnMainThread: or dispatch_async).
   • Print response to console (UI display comes in Spec 003).

Acceptance Criteria

• UI remains responsive (no beachball) during API call.
• "Processing..." indication is shown.
• Image frame is correctly sent to OpenAI.
• Text response is received and printed to console.
