Bump PyTorch pin to nightly dev20260705

[pytorchupdatebot]

Summary

Automated weekly PyTorch pin bump.

• Updates NIGHTLY_VERSION in torch_pin.py to dev20260705
• Updates .ci/docker/ci_commit_pins/pytorch.txt to the corresponding nightly commit hash
• Syncs c10 headers from PyTorch into runtime/core/portable_type/c10/

This PR was created automatically. If CI fails, Claude will attempt to fix issues (up to 3 attempts). If CI still fails, human review will be requested.
