Subject: Fix SyncTeX: download synctex.gz via web proxy, normalize paths,
 smooth zoom

- synctex.gz CDN returns 503; use Overleaf web proxy URL with session cookie
- Normalize synctex paths (collapse /./ segments)
- Pass session cookie to all compile artifact downloads
- Smooth editor zoom: continuous delta, debounced remeasure
