fix(cli): correct WebP MIME type check in handleResponse ('webp' → 'image/webp')

[kuishou68]

Summary

Fixes a bug in src/daemon/client.ts where the MIME type case for WebP images was 'webp' instead of the correct 'image/webp'.

Problem

In handleResponse, the switch statement for determining file extension used the incorrect string 'webp' as the MIME type. Since browsers and servers send image/webp as the MIME type, the case never matched, and all WebP images were saved with a .png extension instead of .webp.

// Before (buggy)
case 'webp':
  extension = '.webp';
  break;

// After (fixed)
case 'image/webp':
  extension = '.webp';
  break;

Testing

WebP screenshots/images returned by the tool will now correctly receive the .webp extension.

Closes #1898
