Community PR checklist

• No unsolicited architecture changes. New crates, new workspace dependencies, changes to grafeo-core/grafeo-engine internals, or new feature flags were either (a) requested in the linked issue or (b) discussed and approved in a GitHub Discussion before this PR was opened.
• No changes to shared infrastructure. CI workflows (.github/workflows/), the root Cargo.toml, codecov.yml, and scripts/ are not modified unless the change is the explicit purpose of this PR.
• No naming or concept conflicts. I have searched the codebase and existing issues/discussions to confirm that any new types, modules, or subsystem names do not duplicate or conflict with existing ones.
