Brandon ThomasandClaude Opus 5.5 71272d5cd7 GPU: fs_adjust compiles under FXC (D3D12); a pipeline build failure falls back to the CPU ...

On D3D12 without DXC, wgpu compiles HLSL with FXC, which aborted on
fs_adjust ("internal error: compilation aborted unexpectedly"). wgpu turns
that into a panic, so every GPU test failed on the Windows runner, and the
app would crash where the same path is taken. A bisect on the Windows
runner pinned it to two cases of adjust()'s switch, Exposure and Selective
Color: both looped over dynamically indexed vector components. They are
now written per channel / per range with the same math (GPU-vs-CPU parity
is unchanged and passes on Metal and on the Windows runner).

Compositor::try_new_with_format catches validation and internal errors
while building the pipelines and returns Err; the canvas then uses the CPU
compositor (once, remembered) instead of crashing.
