feat(ollama): use nexus-core/models as the model store on Windows too

Browse Source 
Windows pulled into %USERPROFILE%\.ollama while ncp and doctor looked in
nexus-core\models. The installer now sets OLLAMA_MODELS for its pulls and moves
an existing default store across first (instant on the same volume, no
refetch), and ollama_manager sets OLLAMA_MODELS on every platform. The env block
was duplicated in two methods, which is why the carve-out existed twice; folded
into _serve_env().
