Dockerfile.dev

# Sandboxed dev container — every make target runs inside this so the host
# stays clean. Has uv + dev tools + a minimal "fake" torch via stubs so unit
# tests work without pulling real PyTorch.
#
# Real ML libs (torch, chronos, timesfm, uni2ts) are NOT installed here — they
# live in the prod images. Unit tests use conftest.py to stub the backends, so
# none of that is needed for `make test-unit`.
