…3341) Covers three gaps found by the test-coverage sweep: - 1x1 single-pixel source and no-source rasters, all 4 backends - Inf-friction barrier is impassable like NaN/zero, all 4 backends - attrs/coords/dims preservation, plus lat/lon dim-name passthrough Tests only; no source change. All ran and passed on a CUDA host (numpy, cupy, dask+numpy, dask+cupy).

Closes #3341.
Adds tests for three coverage gaps in
cost_distance. Tests only, no source change.What's new
res,crs), coords, and dim names. Includes alat/loncase to catch any silent rename toy/x.Verification
All 17 new cases ran and passed on a CUDA host (numpy, cupy, dask+numpy, dask+cupy). No GPU cases were skipped. The full
test_cost_distance.pyis green: 72 passed.All three behaviors were already correct in the source. This just pins them so a future change can't break them quietly.
