On Windows, GPU UI test binaries crashed with STATUS_ACCESS_VIOLATION
whenever two of their tests ran at once: arbitrary_rotation_preview 3
runs in 4 on main, and color_managed_canvas, crop_default_mode,
drag_preview_canvas and full_res_preview at random. egui_kittest
prefers a CPU adapter, which on Windows is WARP over DX12, and a dump
puts the fault inside d3d10warp.dll with two WARP devices rendering on
parallel test threads. Bare egui harnesses with no PhotoCraft code
crash the same way, and Vulkan or GL never does. CI's Windows runners
have no GPU, so they run on WARP too.
Three binaries already held a per-binary lock for the same class of
driver bug (Mesa llvmpipe and RADV, #194; libvulkan with NVIDIA and
lavapipe). That lock now lives once in photocraft-testkit
(`gpu_lock`, with the reasons) and every test in the twelve GPU test
binaries without it takes it on its first line. Under nextest each
test is its own process and the lock is free.

* Camera Raw: interactive histogram, clipping warnings and scopes (part of #215)
- RGB histogram of the preview proxy (algo::histogram), drawn as RGB ribbons;
Before/After, five draggable tonal zones, shadow/highlight clipping warnings
(U/O) and Alt-drag channel diagnostics.
- Pixel hover readout, up to nine RGB/Lab colour samplers (S), an ICC-managed
vectorscope (algo::vectorscope) with skin-tone line, and a floating scope panel.
- Settings regrouped as Light, Color, Effects, Curve, Color Mixer, Color Grading
and Detail; Camera Raw labels translated through the cameraRaw context.
- One point-curve editor (point_curve.rs) shared by Camera Raw, the Curves dialog
and adjustment-layer Properties; fixes Camera Raw curve points not dragging.
- Double-clicking a Camera Raw smart filter reopens the Camera Raw dialog with its
settings and updates that filter, instead of the generic parameter form.
- New point curves are validated (2-16 points, increasing inputs); stored Smart
Filters keep loading.
- camera_raw_bench for P31/P36 (not enforced until a baseline includes them).
