Add message resonance review template

[contentincubator2-ops]

Summary

Add a template for reviewing which claims, hooks, and ideas create the strongest audience response.

Why

Weekly learning should focus on resonance and conversation quality, not only impressions.

Scope

• create a review template
• capture winners, losers, and objections
• capture who responded, not just how many responded
• connect learnings to next-week iteration choices

Acceptance criteria

• a reusable resonance review template exists
• it can be used alongside the performance-review skill
• it is understandable without internal context
