Landlock is only supported on Linux with the sandbox-landloc

Error message

Landlock is only supported on Linux with the sandbox-landlock feature

What it means

Stub-implementation error: this LandlockSandbox::new() only compiles when NOT (Linux AND feature sandbox-landlock), so reaching it means the binary was built without the sandbox-landlock Cargo feature or for a non-Linux target. It is a build-configuration fact, not a runtime environment failure — the backend simply does not exist in this binary.

Solutions

1. Rebuild with --features sandbox-landlock on a Linux target
2. Use the platform-appropriate backend (Seatbelt on macOS, AppContainer on Windows)
3. Check backend availability at runtime and skip landlock selection on unsupported builds
