…ction params (#31714) Gather is a pure data-movement op (elements are copied, never interpreted in shader arithmetic), so int64 can be supported safely. int64 (stored as vec2<u32>) is copied losslessly via the raw storage-word path, preserving the full 64-bit value instead of the truncating i32 value type used by arithmetic kernels. int64 is only added to the "T" constraint when the enable_int64 provider option is set. This PR also refactor the int64-migrated kernels' factory functions to take the version range as runtime function parameters instead of template parameters (StartVersion/EndVersion). This removes the explicit template instantiations (reducing binary size) and eliminates the duplication of version ranges between the instantiations and the registrations in webgpu_execution_provider.cc; the ranges now live only at the registration site. (This is a follow up fix of #31049 )
### Description - Adds the WebGPU enableRobustness provider option to control Dawn robust buffer access for ORT-created devices. - Exposes the boolean option through the shared JavaScript type surface for the native Node.js WebGPU binding. - Keeps robustness independent from validationMode and preserves build-specific defaults: enabled in Debug, disabled in Release and RelWithDebInfo. - Handles the process-global WebGPU device lifecycle: the first created device establishes the value; later conflicts and requests for external devices are ignored with a warning. - Does not forward the option through browser/WASM WebGPU, where standard WebGPU APIs cannot configure Dawn toggle chains. - Adds focused native coverage for explicit values, defaults, invalid input, validation independence, conflicts, compile-only contexts, and external devices. ### Motivation and Context Dawn buffer robustness is a device-creation setting that is separate from validation. ONNX Runtime previously enabled Dawn's disable_robustness toggle unconditionally, so native users could not request robust buffer access or configure the safety/performance tradeoff independently. This change exposes that choice for native WebGPU device creation while making the shared-device behavior explicit. It keeps the performance-oriented non-Debug default and enables the safer Debug default. ### Testing - build\Windows\Release\Release\onnxruntime_provider_test.exe --gtest_filter=WebGpuContextTest.* (8 tests passed) - npm run prebuild --prefix js/web - npx prettier --check common/lib/inference-session.ts web/lib/wasm/session-options.ts web/test/test-types.ts
