catbot 27d7e84cb3 feat(webgpu-rt): atomic pixel accumulator + raysPerPixel for >1 ray/pixel/bounce (#30) ... wfAccum becomes array<atomic<u32>> (4 slots/pixel, f32 bit patterns — same 16 B/pixel footprint) and rtAccumulate CASes each channel, so N rays for one pixel may resolve in the same SHADE pass without the read-modify-write racing. GENERATE clears with atomicStore (bitcast(0.0) == 0u); RESOLVE atomicLoads + bitcasts the vec4 it hands runResolve. Capacity half: RTPass::raysPerPixel (default 1) scales the wavefront ray/hit/payload buffers to raysPerPixel·W·H rays per bounce so the per-light emits actually fit instead of being dropped by rtEmitRay's capacity guard. The accumulator stays per-pixel. No flag-gating: uncontended the CAS succeeds first try — RTStress SHADE stays at its documented ~1.0 ms and master-vs-branch renders are byte-identical, so single-ray consumers pay nothing.
