Move the ExecuTorch pin to 1.6.0.dev20261008, the newest nightly wheel on the index, with the source commit read from that wheel (e132612f3bf9d5c5b7c9012a398851aa9c3fee27). This is the output of .github/scripts/update_executorch_pin.py --track nightly followed by the workflow's uv lock --refresh --prerelease=allow, as the scheduled job would produce.

Why now

The scheduled bump (#4803) proposes 1.6.0.dev20261007, which is cut before pytorch/executorch#23547. That change makes the Python bindings return device memory for the outputs of a method whose outputs are not memory planned. Without it, executorch-runtime-test fails at load_model_device_resident.py with Allocation not found in copy_device_to_device, on main and on every open pull request, so the job never reaches the C++ delegate tests. The 1.6.0.dev20261008 wheel is cut from pytorch/executorch main two commits after #23547 and contains it.

Test plan

The pin consistency checks and the ExecuTorch delegate build and test lane run on this pull request.
