Pre-built PyTorch cu128 wheels only ship native kernels for sm_80/86/89/90. Without this, Blackwell GPU users get "no kernel image is available for execution on the device" at runtime.

feat: add Blackwell GPU (sm_120) CUDA support (#401 )

Set TORCH_CUDA_ARCH_LIST in the CUDA build step to include 12.0+PTX
for forward compatibility with Blackwell GPUs (RTX 5070 Ti, 5080, etc).

Pre-built PyTorch cu128 wheels only ship native kernels for sm_80/86/89/90.
Without this, Blackwell GPU users get "no kernel image is available for
execution on the device" at runtime.

Fixes #386

fix: prevent intermittent clip splitting failures (#403 )

Two changes to address the race condition causing "Failed to split clip":

Backend (stories.py): Added with_for_update() to the item query in
split_story_item so concurrent requests for the same clip are
serialized via a row lock instead of racing.

Frontend (StoryTrackEditor.tsx): Guard handleSplit with
splitItem.isPending to prevent rapid double-clicks from firing
multiple mutations before the first completes.

Fixes #366
