fix(explorer): make uv sync install the web deps for Streamlit Cloud#42
Merged
Conversation
Streamlit Community Cloud installs deps with `uv sync` when a uv.lock is present (it ignores requirements.txt), and `uv sync` pulls the base package + default groups but NOT optional-dependency extras -- so the deployed app got the core library without Streamlit/scipy/etc. and crashed on `import scipy`. Add a `deploy` default dependency-group referencing the `explorer` extra (single source of truth) so a plain `uv sync` installs the web stack. Dependency groups are dev-time only, so `pip install simcenter-dlml` stays lightweight (verified: scipy/streamlit appear only under extras in the wheel metadata).
