chihlasm 1c0f912cf6 perf: resize images server-side before sending to Claude vision
- Resize to 1568px max (Claude's efficient ceiling) via Pillow
- Convert PNG screenshots to JPEG q85 (~5MB → ~200KB typical)
- Cap at 3 images per message (~4,800 token budget max)
- Graceful fallback if Pillow unavailable (Claude auto-resizes)
- Add Pillow + libjpeg/zlib deps to requirements + Dockerfile
