Adds an 8^3 = 512-instance TLAS pick test that shoots one analytically determined ray through a rayQuery=true PlainComputeShader and checks the read-back committed hit (customIndex 484, t 40.75). 512 instances sit in the < 8193 regime that the hardcoded 16384-leaf start used to miss, so the example fails fast if the shim regresses. Verified in Firefox/WebGPU: "[RayQueryPick] PASS". Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
