Delete scripts/benchmark/core/device_info.py re-export shim (#2474 P1) #2490

Summary

UniLab issue #2474 (shim/compatibility audit) flags scripts/benchmark/core/device_info.py as a pure re-export shim ("moved in issue #1240") that re-exports unilab.utils.device names with no added behavior.

This change deletes the shim and removes the re-export from scripts/benchmark/core/__init__.py; all benchmark consumers under scripts/benchmark/ (19 scripts) now import directly from unilab.utils.device.

Files changed

• Deleted: scripts/benchmark/core/device_info.py
• Modified: scripts/benchmark/core/__init__.py (removed re-export)
• Modified: 19 benchmark scripts under scripts/benchmark/ (compute/env/physics/rl/torch_env) to import from unilab.utils.device directly

Guards

• uv run pytest -q tests/utils/test_device.py tests/benchmark tests/utils/test_utils_package_policy.py — 168 passed, 1 skipped
• uv run python scripts/benchmark/smoke_test.py — module-mode 34/34, script-mode 35/35 passed
• uv run ruff check on all changed files — clean
