fix: make review-definition checklist concrete with domain-neutral violation patterns

Reviewer was passing perstack.toml with file paths, Deliverables sections,
internal API names, and implementation details because the checklist was too
abstract ("contains only domain constraints"). Add specific flag criteria:

- Output locations/structure (where to place results, artifact enumeration)
- Internal APIs of specified tools (methods/hooks/functions — derivable)
- Named alternatives to reject (implicit from positive specification)
- Implementation approach (how vs what)
- Code snippets, data schemas, step-by-step procedures

All patterns are domain-neutral per Design Principle 3 (Domain Agnosticism).

+For each non-coordinator instruction, flag (✗) if any of the following appear:
+- Output locations or structure — dictates where to place results or enumerates specific artifacts to produce. The instruction should describe what the output must accomplish, not its shape.
+- Internal APIs of specified tools — names specific methods, hooks, functions, or parameters of a tool. "Use tool X" is the constraint; how to use its API is derivable.
+- Named alternatives to reject — lists tools or approaches NOT to use. Specifying what to use implicitly excludes alternatives.
+- Implementation approach — describes how to build something rather than what constraints the result must satisfy.
+- Code snippets, data schemas, or step-by-step procedures.
