Pull Request resolved: #20391 Registers `aten.sigmoid.default` in the `cases.py` op-test framework: a `_sigmoid_suite` (hard-coded shapes + a saturation case over a `linspace(-12, 12)` input) that `generate_op_tests` exports and compares to an fp64 torch golden on Dawn. Also adds `test/ops/sigmoid/test_sigmoid.py` (`SigmoidModule` + `N` + `_det_input` + an export-delegation/eager smoke test) and the `aten.sigmoid.default` partitioner-allowlist entry in `tester.py`. ghstack-source-id: 397026520 @exported-using-ghexport Differential Revision: [D108793159](https://our.internmc.facebook.com/intern/diff/D108793159/)

Pull Request resolved: #20392 Adds `aten.squeeze_copy.dims` and `aten.unsqueeze_copy.default` to the WebGPU delegate. Both are numel-preserving shape ops; on a dense row-major buffer backend they are the same flat copy as `view_copy` — only the shape metadata differs (mirrors the Vulkan delegate, which routes both through `add_view_copy_node`). Composition (no new kernel): - `squeeze/Squeeze.cpp` — reads `args = [self, dims, out]`, ignores the AOT-fixed `dims`, calls `add_flat_copy(graph, in, out)` from `runtime/ops/view_copy/view_copy.h`. - `unsqueeze/Unsqueeze.cpp` — reads `args = [self, dim, out]`, ignores the AOT-fixed `dim`, calls `add_flat_copy(graph, in, out)`. ghstack-source-id: 397026523 @exported-using-ghexport Differential Revision: [D108793153](https://our.internmc.facebook.com/intern/diff/D108793153/)
….py op-test framework) Pull Request resolved: #20393 Registers `aten.squeeze_copy.dims` and `aten.unsqueeze_copy.default` in the `cases.py` op-test framework: a `_squeeze_suite` of 3 configs (squeeze leading/middle/multiple size-1 dims) and a `_unsqueeze_suite` of 3 configs (insert dim at front/middle/last) that `generate_op_tests` exports via `VulkanPartitioner` and compares to a torch golden on Dawn. Also adds `test/ops/squeeze/test_squeeze.py` (`SqueezeModule` + `CONFIGS` + `_op_delegated` smoke test), `test/ops/unsqueeze/test_unsqueeze.py` (`UnsqueezeModule` + `CONFIGS` + `_op_delegated` smoke test), and the two partitioner-allowlist entries in `tester.py`. ghstack-source-id: 397026525 @exported-using-ghexport Differential Revision: [D108793152](https://our.internmc.facebook.com/intern/diff/D108793152/)
