Fix dependency conflict, Laplacian blend arg order, pyrightconfig

requirements.txt
- Remove streamlit (not imported anywhere — leftover from early Streamlit
prototype; was causing a protobuf version conflict)
- Fix protobuf constraint: >=3.20,<4.0 → >=4.25.3,<6.0 so mediapipe
0.10.14 (which requires protobuf>=4.25.3) can install without conflict

pipeline/full_pipeline.py
- Fix swapped argument order in laplacian_blend() call.
Was: laplacian_blend(target, swapped, mask) — put the original target
face back inside the face mask, undoing the swap.
Now: laplacian_blend(swapped, target, mask) — swapped face inside mask,
target background outside. Same bug fixed in web_app.py already.

web_app.py
- Same laplacian_blend argument-order fix (swapped, target, face_mask)
- Update protobuf env-var comment for clarity

pyrightconfig.json
- Point to student user's Python 3.10 install so IDE resolves imports
