Document and wire the weight-caching mechanism:
- modal.Volume is a cloud-backed FS independent of the GPU/container;
run 1 downloads weights into /weights, run 2+ reuses them (no GPU time
wasted re-downloading).
- Point downloaders at the mount: HF_HOME/TORCH_HOME/boltz --cache; persist
via weights.commit(), see updates via weights.reload().
- Volume storage costs pennies, separate from GPU = near-free caching.
modal_app.py cofold(): set cache env vars to /weights, reload()/commit()
around the (stubbed) boltz call.
