fix(controller): parse the CUDA UMD version banner from newer drivers

[luminary19]

Summary

NVIDIA driver 610+ renamed the nvidia-smi banner field from CUDA Version: to CUDA UMD Version:, so CUDA detection silently returned nothing on toolkit-less machines running the new driver series (the nvcc fallback masked it elsewhere). The parser moves to a small cuda-version.ts module and accepts both spellings; unit tests cover the old banner, the new banner, and no banner. Fixes #184.

Validation

cd controller
bun run typecheck
bun run lint
bun test ./src/modules/engines/runtimes/cuda-version.test.ts   # 3 pass

Verified live on driver 610.47 (Windows 11, RTX 4070): /runtime/info reports the CUDA version again. Pre-610 banners are unaffected — the old spelling still matches.

UI changes

None.

Risks / rollout notes

None — pure parser widening; the extracted module is consumed only by runtime-info today.

[0xSero]

Verified against main: the regex at runtime-info.ts:179 only matches CUDA Version:, so driver 610+ machines without nvcc silently report no CUDA — this widening fixes it while keeping the old banner. The extraction to cuda-version.ts is clean (both sync and async call sites use the import) and the three-case test suite runs under CI's bun test src.
