Tighten GPU duration to 60s (measured ~12s worst-case GPU time)

Remove temp isolation-test file

Lazy-load cra5/compressai + model inside GPU worker (fix ZeroGPU fork CUDA poison)

TEMP: mini5 deferred compressai import

TEMP: mini4 compressai.ans-only

TEMP: mini3 compressai-only isolation

TEMP: app.py = mini2 heavy-imports isolation

TEMP: mini2 with heavy imports

Restore full app; move model to GPU lazily inside worker

TEMP: minimal ZeroGPU isolation test

Pin torch==2.8.0 for ZeroGPU worker compatibility

Add cuda-init probes

Add CRA5 ERA5 decompression demo
