setup.ps1

<#
  One-shot setup for the SHARP Image2Splat service on a fresh Windows + NVIDIA host.

  Prerequisites (install these first): Python 3.13 (`py -3.13` on PATH), git, and a recent
  NVIDIA driver. Then, from the repo root:

      powershell -ExecutionPolicy Bypass -File setup.ps1               # install, then run in the foreground
      powershell -ExecutionPolicy Bypass -File setup.ps1 -AutoStart    # install, then register the boot Scheduled Task
      powershell -ExecutionPolicy Bypass -File setup.ps1 -NoRun        # install only

  Older CUDA? point at a matching torch wheel index, e.g.:
      powershell -ExecutionPolicy Bypass -File setup.ps1 -TorchIndex https://download.pytorch.org/whl/cu121

  This wraps service\install.ps1 (clones ml-sharp @ the pin, builds the venv, forces the CUDA
  torch build, installs OpenEXR, verifies) and then starts the service or registers auto-start.
