Fixes#5: Add compatibility shim for find_pruneable_heads_and_indices
which was removed in transformers 4.40.0. All 12 GPT2 model files now
use a try/except fallback.
Fixes#6: Add ultra low memory mode for 12GB VRAM systems.
- New memory_mode dropdown: auto, normal, low, ultra
- Auto mode detects available VRAM and selects best mode
- Ultra mode uses ~6GB peak VRAM with aggressive cleanup
- Added VRAM monitoring and logging during generation
Bump version to 1.3.0
