Add Tuist support for project generation

- Add root Project.swift replacing hand-maintained xcodeproj
- Add Tuist.swift and .mise.toml (pins tuist 4.115.1)
- Add Example/ with minimal commandLine app consuming OpenAttributeGraph
- Update build_xcframework.sh to use tuist generate
- Update .gitignore for Tuist-generated files
