* #1590: build effect kernels on first use instead of with the GPU context GpuContext::new built every compute pipeline up front: the compositor's own kernels and ~208 effect kernels. In Chrome on Windows that kept the GPU process busy past its watchdog, so the device was lost ~60 s after every load (#1590); on DirectX 12 with FXC the window took over a minute to appear (#613). The compositor's kernels are still built up front and required. Effect kernels are built the first time a dispatch asks for one, inside the same error scopes, so one a compiler rejects still renders its effects on the CPU. unavailable_kernels lists the failures so far; build_all_kernels builds the rest. RX 6900 XT, Windows: Vulkan context 0.27 s, all effect kernels 0.9 s, GPU tests 77 s -> 26 s; on #1571's DX12/FXC, context ~66 s -> 1.96 s, tests 1306 s -> 252 s, same results. Co-Authored-By: Claude <noreply@anthropic.com> * #1590: compile each kernel family as a shader module of its own Building effect kernels on first use was not enough in Chrome: the page and its frame workers each create a device, every one compiled its required kernels against the single ~460K-character module, and Dawn compiles the module again for each pipeline, so the GPU process still passed its watchdog and the device was lost ~64 s after load (RX 6900 XT, Chrome 155). Each kernel family (FAMILIES) is now common.wgsl + kernels.wgsl + its own file and the files it borrows functions from (at most ~120K characters), built with the family's first kernel; the compositor's kernels, sky and classic3d use small modules of their own. Chrome 155 on Windows / RX 6900 XT, release web build, default flags: main loses the device at ~64 s (60.7 s with ?nogpuworkers); with this, two 100 s runs keep it, and both frame workers get the GPU. Native Vulkan tests unchanged (212 passed, the 3 failures that main has, #1605).
