- Replace iterative tutte_embedding in lib with numpy direct-solve version from example.py
- Import tutte_embedding into example.py from lib instead of defining it locally
- Fix g._embedding -> g.get_embedding() in outer_face
- Add bash completion to run.sh alongside existing zsh completion
- Use nix-shell -p gcc for plantri build step on NixOS

Replaces is_planar(set_embedding=True) calls in pluck and squish so the embedding
stays consistent with inherited positions across reduction steps.

Adds outer face detection via face traversal and signed area, Tutte embedding
for clean planar layouts, and moves g/g_prime/coloring_prime into base Operation
type. Pluck and squish now carry positions and recompute embeddings via is_planar.
