Subject: [PATCH] Adds manual PyPI publishing workflow

Enables on-demand package publishing to PyPI through GitHub Actions workflow dispatch.

Accepts configurable git tag and Python version inputs, builds source distribution with CUDA build skipped, and uploads to PyPI using API token authentication.

Includes validation to prevent publishing when required secrets are missing.
