CI/CD workflows, automation, security scanning, and package distribution.

## Workflows
- **conda-package.yml** — main build/test pipeline (Linux/Windows, Python 3.10-3.14)
- **conda-package-cf.yml** — build/test using only conda-forge channel (Linux/Windows, Python 3.10-3.14)
All build/test workflows cover Python 3.10-3.14 plus free-threaded 3.14t.

- **conda-package.yml** — main build/test pipeline (Linux/Windows)
- **conda-package-cf.yml** — build/test using only conda-forge channel (Linux/Windows)
- **build-with-clang.yml** — Linux Clang compiler compatibility validation
- **build-with-standard-clang.yml** — standard Clang compiler compatibility validation
- **build_pip.yml** — validates editable build

## CI/CD policy
- Keep build matrix (Python versions, platforms) in workflow files only
- Required checks: conda build + test on supported Python versions/platforms in CI
- Artifact naming: `$PACKAGE_NAME $OS Python $VERSION`
- Python 3.14 is expressed as two `include` rows carrying `python_spec` (`3.14.* *_cp314` and `3.14.* *_cp314t`); a bare `--python 3.14` has been observed to select the free-threaded ABI and must not be relied on
- `include` rows create new matrix combinations and inherit nothing, so `runner`/`experimental` must be repeated wherever the job reads them
- Artifact naming: `$PACKAGE_NAME $OS Python $VERSION`, where `$VERSION` is `python_tag` (`3.14` or `3.14t`) when set, otherwise `python`
- Channels: `conda-forge`, `conda-forge/label/python_rc`, Intel channel

Need to extend strategy matrix for GitHub workflows to validate 3.14t also

Added "3.14t" to the matrices

need to add to the conda package workflow too, which requires more robust strategy. See approach in dpctl
