Align Tuist setup with remote branch best practices

- Use Tuist 4.x API (Tuist struct) instead of deprecated Config()
- Add defaultSettings: .none to let xcconfigs drive all build settings
- Add Tuist/Package.swift for Tuist 4.x external dependency support
- Add explicit headers configuration for project headers
- Use .pre(path:) script API with explicit input/output paths
- Rename .mise.toml to mise.toml, update to tuist 4.156.0
- Add Tuist/.build/ and *.xcframework to .gitignore
- Add "Xcode (via Tuist)" section to README.md
- Update Example/Tuist.swift to Tuist 4.x API

+### Xcode (via Tuist)
+
+This project uses [Tuist](https://tuist.dev) to generate the Xcode project for framework builds.
+
+1. Install Tuist (if not already installed):
+   ```shell
+   # via mise
+   mise install tuist
+   # or via Homebrew
+   brew install tuist
+   ```
+
+2. Generate the Xcode project:
+   ```shell
+   tuist generate
+   ```
+
+3. Build using the generated workspace:
+   ```shell
+   xcodebuild build -workspace OpenAttributeGraph.xcworkspace -scheme OpenAttributeGraph -destination 'generic/platform=iOS Simulator'
