Check Impl Against Spec

This one checks your PR implementation against a spec file during code review. It reads spec_context.md, pulls out the concrete commitments (required behaviors, files to change, constraints), then compares them against the actual diff and flags material mismatches in review.json. The smart bit is it ignores harmless differences like naming tweaks and only complains about real problems: missing required behavior, contradictions to spec decisions, or absent migration steps. It folds findings into your existing review output rather than creating separate reports. Useful if your team writes specs before code and wants an automated sanity check that the PR actually delivers what was promised without getting pedantic about implementation details.
