Migrate quaddtype to standalone repository
- Extracted quaddtype from numpy-user-dtypes with full git history - Added CI workflows (build_wheels.yml, build_docs.yml, big_endian.yml, typecheck.yml) - Updated URLs in pyproject.toml and README.md to point to new repository - Added .gitignore, .clang-format, .pre-commit-config.yaml, dependabot.yml - Tag format changed from 'quaddtype-v*' to 'v*' for releases - All paths updated for standalone repository structure
