- Add per-user session/workspace paths to .gitignore so runtime data
(sessions, uploads, memory, attachments, pubmed) is no longer tracked
- Narrow ollama_web_search description to prevent it being chosen over
web_search for news/info queries — it's now explicitly a fallback only
- Add scripts/install-image-deps.sh to install Pillow/torch/rembg deps
- Remove stray root files (1, pdf-pptx.txt, eng.traineddata)
