Fixed WebSocket handler to properly save base64 images to temp files

Output

✅ Bug Fixed: Image Attachments

Root Cause

The WebSocket prompt handler (handleWebSocketPrompt) was receiving base64 data URLs from the client but treating them as file paths directly.

// Before (broken)
const imagePaths = images || [];  // images = ["data:image/png;base64,iVBO..."]
// Passed raw base64 URLs as if they were file paths!

The Fix

Now properly converts base64 data URLs to temp files (matching SSE endpoint behavior):

// After (fixed)
const imagePaths: string[] = [];
if (images && images.length > 0) {
  const tempDir = "/tmp/konui-images";
  for (let i = 0; i < images.length; i++) {
    // Parse: data:image/png;base64,iVBORw0KGgo...
    const base64Match = imageData.match(/^data:image\/([^;]+);base64,(.+)$/);
    const imageBytes = Uint8Array.from(atob(base64Data), c => c.charCodeAt(0));
    await Deno.writeFile(imagePath, imageBytes);
    imagePaths.push(imagePath);  // Now a real file path!
  }
}

Why This Broke

SSE Endpoint WebSocket Handler
✓ Saves images to /tmp/konui-images/ ✗ Was passing raw base64 URLs
✓ Claude can Read the file ✗ Claude couldn't find "file"
