adapter.request_device asked for Limits::default(), which requests desktop-tier compute-shader limits unconditionally even though nothing in iris/iris-core creates a ComputePipeline or writes a @compute stage. That crashed device creation outright on a downlevel GL adapter reporting OpenGL ES 3.0 (no compute at all) -- the Android emulator's EMU_GPU=software/force-gles path, and any real GLES-3.0-only device. New iris_core::device_limits(), shared by both platform backends, zeros exactly the six max_compute_* fields rather than switching to a downlevel Limits preset -- downlevel_webgl2_defaults() also zeros max_storage_buffers_per_shader_stage, which shader.wgsl's vertex stage needs. rigs/gpu-probe's own mirrored limits were updated to match. Not verified against the actual SwiftShader-ES-3.0 crash on-device this pass: the cold boot needed would have force-restarted this checkout's emulator while another session had its own app running on it.
