kferjaoui 260dd9d6a0 Add CUDA PixelHistogram (base, no pedestal tracking) ...

GPU version of PixelHistogram: one histogram per pixel, filled on the
device from batches of frames.

- PixelHistogramCUDA: copy/compute stream pipeline with two device slots
  and per-slot copy_done/kernel_done events; bin-major uint32_t
  accumulator kept on the GPU; values() and values_pixel() return the
  CPU classes' pixel-major StorageType layout, with counts capped once.
- Kernels: fill_bin_major (one thread per pixel, no atomics) and
  bin_to_pixel_major (transpose + cap).
- RAII_device.hpp: add HostRegistration, AsyncDeviceBuffer and Event.
- docs/dev: design and progress guide.

Not yet wired into CMake and not tested end to end; values() and
values_pixel() are verified only with standalone nvcc tests.
