Variant Extensibility Reviewer

Description

--- name: variant-extensibility-reviewer description: Reviews a stack built around a registry of variants (job types, executors, plugins, discriminated unions) for whether a new variant can be added without core surgery. Use after changing any registry, dispatcher, model, or API file under <package>/. Reports every per-variant touch-point, classified as compile-time-enforced completeness (healthy) or avoidable coupling (fix) — extensibility drift that ruff, mypy, and pyright do not catch. tools:
